Daniel Nephin 89f41bddfe Remove TTL from cacheEntryExpiry
This should very slightly reduce the amount of memory required to store each item in
the cache.

It will also enable setting different TTLs based on the type of result. For example
we may want to use a shorter TTL when the result indicates the resource does not exist,
as storing these types of records could easily lead to a DOS caused by
OOM.

Daniel Nephin 7246d8b6cb agent/cache: Reduce differences between notify implementations
These two notify functions are very similar. There appear to be just
enough differences that trying to parameterize the differences may not
improve things.

For now, reduce some of the cosmetic differences so that the material
differences are more obvious.

Daniel Nephin faeaed5d0c agent/cache: Make the return values of getEntryLocked more obvious
Use named returned so that the caller has a better idea of what these
bools mean.

Return early to reduce the scope, and make it more obvious what values
are returned in which cases. Also reduces the number of conditional
expressions in each case.

fix flaky TestReplication_FederationStates test due to race conditions (#7612)
The test had two racy bugs related to memdb references.

The first was when we initially populated data and retained the FederationState objects in a slice. Due to how the `inmemCodec` works these were actually the identical objects passed into memdb.

The second was that the `checkSame` assertion function was reading from memdb and setting the RaftIndexes to zeros to aid in equality checks. This was mutating the contents of memdb which is a no-no.

With this fix, the command:
```
i=0; while /usr/local/bin/go test -count=1 -timeout 30s github.com/hashicorp/consul/agent/consul -run '^(TestReplication_FederationStates)$'; do i=$((i + 1)); printf "$i "; done
```
That used to break on my machine in less than 20 runs is now running 150+ times without any issue.

Might also fix #7575

tests: change default http_max_conns_per_client to 250 to ease tests (#7625)
On recent Mac OS versions, the ulimit defaults to 256 by default, but many
systems (eg: some Linux distributions) often limit this value to 1024.

On validation of configuration, Consul now validates that the number of
allowed files descriptors is bigger than http_max_conns_per_client.

This make some unit tests failing on Mac OS.
Use a less important value in unit test, so tests runs well by default
on Mac OS without need for tuning the OS.

Daniel Nephin c9a87be6ee agent/cache: move typeEntry lookup to the edge
This change moves all the typeEntry lookups to the first step in the exported methods,
and makes unexporter internals accept the typeEntry struct.

This change is primarily intended to make it easier to extract the container of caches
from the Cache type.

It may incidentally reduce locking in fetch, but that was not a goal.

agent: show warning when enable_script_checks is enabled without safty net (#7437)
In order to enforce a bit security on Consul agents, add a new method in agent
to highlight possible security issues.

This does not return an error for now, but might in the future.

For now, it detects issues such as:

This would display this kind of messages:

agent: rewrite checks with proxy address, not local service address (#7518)
Exposing checks is supposed to allow a Consul agent bound to a different
IP address (e.g., in a different Kubernetes pod) to access healthchecks
through the proxy while the underlying service binds to localhost. This
is an important security feature that makes sure no external traffic
reaches the service except through the proxy.

However, as far as I can tell, this is subtly broken in the case where
the Consul agent cannot reach the proxy over localhost.

If a proxy is configured with: `{ LocalServiceAddress: "127.0.0.1",
Checks: true }`, as is typical with a sidecar proxy, the Consul checks
are currently rewritten to `127.0.0.1:<random port>`. A Consul agent
that does not share the loopback address cannot reach this address. Just
to make sure I was not misunderstanding, I tried configuring the proxy
with `{ LocalServiceAddress: "<pod ip>", Checks: true }`. In this case,
while the checks are rewritten as expected and the agent can reach the
dynamic port, the proxy can no longer reach its backend because the
traffic is no longer on the loopback interface.

I think rewriting the checks to use `proxy.Address`, the proxy's own
address, is more correct in this case. That is the IP where the proxy
can be reached, both by other proxies and by a Consul agent running on
a different IP. The local service address should continue to use
`127.0.0.1` in most cases.

proxycfg: support path exposed with non-HTTP2 protocol (#7510)
If a proxied service is a gRPC or HTTP2 service, but a path is exposed
using the HTTP1 or TCP protocol, Envoy should not be configured with
`http2ProtocolOptions` for the cluster backing the path.

A situation where this comes up is a gRPC service whose healthcheck or
metrics route (e.g. for Prometheus) is an HTTP1 service running on
a different port. Previously, if these were exposed either using
`Expose: { Checks: true }` or `Expose: { Paths: ... }`, Envoy would
still be configured to communicate with the path over HTTP2, which would
not work properly.

config: validate system limits against limits.http_max_conns_per_client (#7434)
I spent some time today on my local Mac to figure out why Consul 1.6.3+
was not accepting limits.http_max_conns_per_client.

This adds an explicit check on number of file descriptors to be sure
it might work (this is no guarantee as if many clients are reaching
the agent, it might consume even more file descriptors)

Anyway, many users are fighting with RLIMIT_NOFILE, having a clear
message would allow them to figure out what to fix.

Example of message (reload or start):

```
2020-03-11T16:38:37.062+0100 [ERROR] agent: Error starting agent: error="system allows a max of 512 file descriptors, but limits.http_max_conns_per_client: 8192 needs at least 8212"

Add config entry for terminating gateways (#7545)
This config entry will be used to configure terminating gateways.

It accepts the name of the gateway and a list of services the gateway will represent.

For each service users will be able to specify: its name, namespace, and additional options for TLS origination.

wan federation via mesh gateways (#6884)
This is like a Möbius strip of code due to the fact that low-level components (serf/memberlist) are connected to high-level components (the catalog and mesh-gateways) in a twisty maze of references which make it hard to dive into. With that in mind here's a high level summary of what you'll find in the patch:

There are several distinct chunks of code that are affected:

* new flags and config options for the server

* retry join WAN is slightly different

* retry join code is shared to discover primary mesh gateways from secondary datacenters

* because retry join logic runs in the *agent* and the results of that
  operation for primary mesh gateways are needed in the *server* there are
  some methods like `RefreshPrimaryGatewayFallbackAddresses` that must occur
  at multiple layers of abstraction just to pass the data down to the right
  layer.

* new cache type `FederationStateListMeshGatewaysName` for use in `proxycfg/xds` layers

* the function signature for RPC dialing picked up a new required field (the
  node name of the destination)

* several new RPCs for manipulating a FederationState object:
  `FederationState:{Apply,Get,List,ListMeshGateways}`

* 3 read-only internal APIs for debugging use to invoke those RPCs from curl

* raft and fsm changes to persist these FederationStates

* replication for FederationStates as they are canonically stored in the
  Primary and replicated to the Secondaries.

* a special derivative of anti-entropy that runs in secondaries to snapshot
  their local mesh gateway `CheckServiceNodes` and sync them into their upstream
  FederationState in the primary (this works in conjunction with the
  replication to distribute addresses for all mesh gateways in all DCs to all
  other DCs)

* a "gateway locator" convenience object to make use of this data to choose
  the addresses of gateways to use for any given RPC or gossip operation to a
  remote DC. This gets data from the "retry join" logic in the agent and also
  directly calls into the FSM.

* RPC (`:8300`) on the server sniffs the first byte of a new connection to
  determine if it's actually doing native TLS. If so it checks the ALPN header
  for protocol determination (just like how the existing system uses the
  type-byte marker).

* 2 new kinds of protocols are exclusively decoded via this native TLS
  mechanism: one for ferrying "packet" operations (udp-like) from the gossip
  layer and one for "stream" operations (tcp-like). The packet operations
  re-use sockets (using length-prefixing) to cut down on TLS re-negotiation
  overhead.

* the server instances specially wrap the `memberlist.NetTransport` when running
  with gateway federation enabled (in a `wanfed.Transport`). The general gist is
  that if it tries to dial a node in the SAME datacenter (deduced by looking
  at the suffix of the node name) there is no change. If dialing a DIFFERENT
  datacenter it is wrapped up in a TLS+ALPN blob and sent through some mesh
  gateways to eventually end up in a server's :8300 port.

* a new flag when launching a mesh gateway via `consul connect envoy` to
  indicate that the servers are to be exposed. This sets a special service
  meta when registering the gateway into the catalog.

* `proxycfg/xds` notice this metadata blob to activate additional watches for
  the FederationState objects as well as the location of all of the consul
  servers in that datacenter.

* `xds:` if the extra metadata is in place additional clusters are defined in a
  DC to bulk sink all traffic to another DC's gateways. For the current
  datacenter we listen on a wildcard name (`server.<dc>.consul`) that load
  balances all servers as well as one mini-cluster per node
  (`<node>.server.<dc>.consul`)

* the `consul tls cert create` command got a new flag (`-node`) to help create
  an additional SAN in certs that can be used with this flavor of federation.

agent: configuration reload preserves check's statuses for services (#7345)
This fixes issue #7318

Between versions 1.5.2 and 1.5.3, a regression has been introduced regarding health
of services. A patch #6144 had been issued for HealthChecks of nodes, but not for healthchecks
of services.

What happened when a reload was:

1. save all healthcheck statuses
2. cleanup everything
3. add new services with healthchecks

In step 3, the state of healthchecks was taken into account locally,
so at step 3, but since we cleaned up at step 2, state was lost.

This PR introduces the snap parameter, so step 3 can use information from step 1

xDS Mesh Gateway Resolver Subset Fixes (#7294)
* xDS Mesh Gateway Resolver Subset Fixes

The first fix was that clusters were being generated for every service resolver subset regardless of there being any service instances of the associated service in that dc. The previous logic didn’t care at all but now it will omit generating those clusters unless we also have service instances that should be proxied.

The second fix was to respect the DefaultSubset of a service resolver so that mesh-gateways would configure the endpoints of the unnamed subset cluster to only those endpoints matched by the default subsets filters.

* Refactor the gateway endpoint generation to be a little easier to read

agent: ensure node info sync and full sync. (#7189)
This fixes #7020.

There are two problems this PR solves:
  * if the node info changes it is highly likely to get service and check registration permission errors unless those service tokens have node:write. Hopefully services you register don’t have this permission.
  * the timer for a full sync gets reset for every partial sync which means that many partial syncs are preventing a full sync from happening

Instead of syncing node info last, after services and checks, and possibly saving one RPC because it is included in every service sync, I am syncing node info first. It is only ever going to be a single RPC that we are only doing when node info has changed. This way we are guaranteed to sync node info even when something goes wrong with services or checks which is more likely because there are more syncs happening for them.

Minor Non-Functional Updates (#7215)
* Cleanup the discovery chain compilation route handling

Nothing functionally should be different here. The real difference is that when creating new targets or handling route destinations we use the router config entries name and namespace instead of that of the top level request. Today they SHOULD always be the same but that may not always be the case. This hopefully also makes it easier to understand how the router entries are handled.

* Refactor a small bit of the service manager tests in oss

We used to use the stringHash function to compute part of the filename where things would get persisted to. This has been changed in the core code to calling the StringHash method on the ServiceID type. It just so happens that the new method will output the same value for anything in the default namespace (by design actually). However, logically this filename computation in the test should do the same thing as the core code itself so I updated it here.

Also of note is that newer enterprise-only tests for the service manager cannot use the old stringHash function at all because it will produce incorrect results for non-default namespaces.

Note that in the case of getting a services health by its id, we still

service with that ID existing. There isn't really a way around it though
as ACLs are meant to check service names.

Currently when using the built-in CA provider for Connect, root certificates are valid for 10 years, however secondary DCs get intermediates that are valid for only 1 year. There is no mechanism currently short of rotating the root in the primary that will cause the secondary DCs to renew their intermediates.
This PR adds a check that renews the cert if it is half way through its validity period.

In order to be able to test these changes, a new configuration option was added: IntermediateCertTTL which is set extremely low in the tests.

Aestek 5dc8875bd3 agent: do not deregister service checks twice (#6168)
Deregistering a service from the catalog automatically deregisters its
checks, however the agent still performs a deregister call for each
service checks even after the service has been deregistered.
With ACLs enabled this results in logs like:
"message:consul: "Catalog.Deregister" RPC failed to server
server_ip:8300: rpc error making call: rpc error making call: Unknown
check 'check_id'"
This change removes associated checks from the agent state when
deregistering a service, which results in less calls to the servers and
supresses the error logs.

Intentions ACL enforcement updates (#7028)
* Renamed structs.IntentionWildcard to structs.WildcardSpecifier

* Refactor ACL Config

Get rid of remnants of enterprise only renaming.

Add a WildcardName field for specifying what string should be used to indicate a wildcard.

* Add wildcard support in the ACL package

For read operations they can call anyAllowed to determine if any read access to the given resource would be granted.

For write operations they can call allAllowed to ensure that write access is granted to everything.

* Make v1/agent/connect/authorize namespace aware

* Update intention ACL enforcement

This also changes how intention:read is granted. Before the Intention.List RPC would allow viewing an intention if the token had intention:read on the destination. However Intention.Match allowed viewing if access was allowed for either the source or dest side. Now Intention.List and Intention.Get fall in line with Intention.Matches previous behavior.

Due to this being done a few different places ACL enforcement for a singular intention is now done with the CanRead and CanWrite methods on the intention itself.

* Refactor Intention.Apply to make things easier to follow.

Updates to allow for Namespacing ACL resources in Consul Enterp… (#6675)
Main Changes:

• method signature updates everywhere to account for passing around enterprise meta.
• populate the EnterpriseAuthorizerContext for all ACL related authorizations.
• ACL resource listings now operate like the catalog or kv listings in that the returned entries are filtered down to what the token is allowed to see. With Namespaces its no longer all or nothing.
• Modified the acl.Policy parsing to abstract away basic decoding so that enterprise can do it slightly differently. Also updated method signatures so that when parsing a policy it can take extra ent metadata to use during rules validation and policy creation.

Secondary Changes:

• Moved protobuf encoding functions out of the agentpb package to eliminate circular dependencies.
• Added custom JSON unmarshalers for a few ACL resource types (to support snake case and to get rid of mapstructure)
• AuthMethod validator cache is now an interface as these will be cached per-namespace for Consul Enterprise.
• Added checks for policy/role link existence at the RPC API so we don’t push the request through raft to have it fail internally.
• Forward ACL token delete request to the primary datacenter when the secondary DC doesn’t have the token.
• Added a bunch of ACL test helpers for inserting ACL resource test data.

ACL Authorizer overhaul (#6620)
* ACL Authorizer overhaul

To account for upcoming features every Authorization function can now take an extra *acl.EnterpriseAuthorizerContext. These are unused in OSS and will always be nil.

Additionally the acl package has received some thorough refactoring to enable all of the extra Consul Enterprise specific authorizations including moving sentinel enforcement into the stubbed structs. The Authorizer funcs now return an acl.EnforcementDecision instead of a boolean. This improves the overall interface as it makes multiple Authorizers easily chainable as they now indicate whether they had an authoritative decision or should use some other defaults. A ChainedAuthorizer was added to handle this Authorizer enforcement chain and will never itself return a non-authoritative decision.

• CA Root Pruning

Also added the StopAll call into the Server Shutdown method to ensure all leader routines get killed off when shutting down.

ui: UI Release Merge (ui-staging merge) (#6527)
## HTTPAdapter (#5637)

## Ember upgrade 2.18 > 3.12 (#6448)

### Proxies can no longer get away with not calling _super

This means that we can't use create anymore to define dynamic methods.
Therefore we dynamically make 2 extended Proxies on demand, and then
create from those. Therefore we can call _super in the init method of
the extended Proxies.

### We aren't allowed to reset a service anymore

We never actually need to now anyway, this is a remnant of the refactor
from browser based confirmations. We fix it as simply as possible here
but will revisit and remove the old browser confirm functionality at a
later date

### Revert classes to use ES5 style to workaround babel transp. probs

Using a mixture of ES6 classes (and hence super) and arrow functions
means that when babel transpiles the arrow functions down to ES5, a
reference to this is moved before the call to super, hence causing a js
error.

Furthermore, we the testing environment no longer lets use use
apply/call on the constructor.

These errors only manifests during testing (only in the testing
environment), the application itself runs fine with no problems without
this change.

Using ES5 style class definitions give us freedom to do all of the above
without causing any errors, so we reverted these classes back to ES5
class definitions

### Skip test that seems to have changed due to a change in RSVP timing

This test tests a usecase/area of the API that will probably never ever
be used, it was more testing out the API. We've skipped the test for now
as this doesn't affect the application itself, but left a note to come
back here later to investigate further

### Remove enumerableContentDidChange

Initial testing looks like we don't need to call this function anymore,
the function no longer exists

### Rework Changeset.isSaving to take into account new ember APIs

Setting/hanging a computedProperty of an instantiated object no longer
works. Move to setting it on the prototype/class definition instead

### Change how we detect whether something requires listening

New ember API's have changed how you can detect whether something is a
computedProperty or not. It's not immediately clear if its even possible
now. Therefore we change how we detect whether something should be
listened to or not by just looking for presence of `addEventListener`

### Potentially temporary change of ci test scripts to ensure deps exist

All our tooling scripts run through a Makefile (for people familiar with
only using those), which then call yarn scripts which can be called
independently (for people familar with only using yarn).

The Makefile targets always check to make sure all the dependencies are
installed before running anything that requires them (building, testing
etc).

The CI scripts/targets didn't follow this same route and called the yarn
scripts directly (usually CI builds a cache of the dependencies first).

For some reason this cache isn't doing what it usually does, and it
looks as though, in CI, ember isn't installed.

This commit makes the CI scripts consistently use the same method as all

required > call yarn script). This should install the dependencies if
for some reason the CI cache building doesn't complete/isn't successful.

Potentially this commit may be reverted if, the root of the problem is
elsewhere, although consistency is always good, so it might be a good
idea to leave this commit as is even if we need to debug and fix things
elsewhere.

### Make test-parallel consistent with the rest of the tooling scripts

As we are here making changes for CI purposes (making test-ci
consistent), we spotted that test-parallel is also inconsistent and also
the README manual instructions won't work without `ember` installed
globally.

This commit makes everything consistent and changes the manual
instructions to use the local ember instance that gets installed via
yarn

### Re-wrangle catchable to fit with new ember 3.12 APIs

In the upgrade from ember 3.8 > 3.12 the public interfaces for
ComputedProperties have changed slightly. `meta` is no longer a public
property of ComputedProperty but of a ComputedDecoratorImpl mixin
instead.

7e4ba1096e/packages/%40ember/-internals/metal/lib/computed.ts (L725)

There seems to be no way, by just using publically available
methods, to replicate this behaviour so that we can create our own
'ComputedProperty` factory via injecting the ComputedProperty class as
we did previously.

3f333bada1/ui-v2/app/utils/computed/factory.js (L1-L18)

Instead we dynamically hang our `Catchable` `catch` method off the
instantiated ComputedProperty. In doing it like this `ComputedProperty`
has already has its `meta` method mixed in so we don't have to manually
mix it in ourselves (which doesn't seem possible)

This functionality is only used during our work in trying to ensure
our EventSource/BlockingQuery work was as 'ember-like' as possible (i.e.
using the traditional Route.model hooks and ember-like Controller
properties). Our ongoing/upcoming work on a componentized approach to
data a.k.a `<DataSource />` means we will be able to remove the majority
of the code involved here now that it seems to be under an amount of
flux in ember.

connect: connect CA Roots in secondary datacenters should use a SigningKeyID derived from their local intermediate (#6513)
This fixes an issue where leaf certificates issued in secondary
datacenters would be reissued very frequently (every ~20 seconds)
because the logic meant to detect root rotation was errantly triggering
because a hash of the ultimate root (in the primary) was being compared
against a hash of the local intermediate root (in the secondary) and
always failing.

agent: cache notifications work after error if the underlying RPC returns index=1 (#6547)
Fixes #6521

Ensure that initial failures to fetch an agent cache entry using the
notify API where the underlying RPC returns a synthetic index of 1
correctly recovers when those RPCs resume working.

The bug in the Cache.notifyBlockingQuery used to incorrectly "fix" the
index for the next query from 0 to 1 for all queries, when it should
have not done so for queries that errored.

Also fixed some things that made debugging difficult:

- config entry read/list endpoints send back QueryMeta headers
- xds event loops don't swallow the cache notification errors

Expand the QueryOptions and QueryMeta interfaces (#6545)
In a previous PR I made it so that we had interfaces that would work enough to allow blockingQueries to work. However to complete this we need all fields to be settable and gettable.

Notes:
   • If Go ever gets contracts/generics then we could get rid of all the Getters/Setters
   • protoc / protoc-gen-gogo are going to generate all the getters for us.
   • I copied all the getters/setters from the protobuf funcs into agent/structs/protobuf_compat.go
   • Also added JSON marshaling funcs that use jsonpb for protobuf types.

Expose HTTP-based paths through Connect proxy (#6446)
Fixes: #5396

This PR adds a proxy configuration stanza called expose. These flags register
listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only
listening on the loopback interface, while still accepting traffic from non
Connect-enabled services.

Under expose there is a boolean checks flag that would automatically expose all
registered HTTP and gRPC check paths.

This stanza also accepts a paths list to expose individual paths. The primary
use case for this functionality would be to expose paths for third parties like
Prometheus or the kubelet.

Listeners for requests to exposed paths are be configured dynamically at run
time. Any time a proxy, or check can be registered, a listener can also be
created.

In this initial implementation requests to these paths are not
authenticated/encrypted.

connect: intermediate CA certs generated with the vault provider lack URI SANs (#6491)
This only affects vault versions >=1.1.1 because the prior code
accidentally relied upon a bug that was fixed in
https://github.com/hashicorp/vault/pull/6505

The existing tests should have caught this, but they were using a
vendored copy of vault version 0.10.3. This fixes the tests by running
an actual copy of vault instead of an in-process copy. This has the
added benefit of changing the dependency on vault to just vault/api.

Also update VaultProvider to use similar SetIntermediate validation code
as the ConsulProvider implementation.

Add support for implementing new requests with protobufs instea… (#6502)
* Add build system support for protobuf generation

This is done generically so that we don’t have to keep updating the makefile to add another proto generation.

Note: anything not in the vendor directory and with a .proto extension will be run through protoc if the corresponding namespace.pb.go file is not up to date.

If you want to rebuild just a single proto file you can do so with: make proto-rebuild PROTOFILES=<list of proto files to rebuild>

Providing the PROTOFILES var will override the default behavior of finding all the .proto files.

* Start adding types to the agent/proto package

These will be needed for some other work and are by no means comprehensive.

* Add ability to resolve/fixup the agentpb.ACLLinks structure in the state store.

* Use protobuf marshalling of raft requests instead of msgpack for protoc generated types.

This does not change any encoding of existing types.

* Removed structs package automatically encoding with protobuf marshalling

Instead the caller of raftApply that wants to opt-in to protobuf encoding will have to call `raftApplyProtobuf`

* Run update-vendor to fixup modules.txt

Nothing changed as far as dependencies go but the ordering of modules in that file depends on the time they are first seen and its not alphabetical.

* Rename some things and implement the structs.RPCInfo interface bits

agentpb.QueryOptions and agentpb.WriteRequest implement 3 of the 4 RPCInfo funcs and the new TargetDatacenter message type implements the fourth.

* Use the right encoding function.

* Renamed agent/proto package to agent/agentpb to prevent package name conflicts

* Update modules.txt to fix ordering

* Change blockingQuery to take in interfaces for the query options and meta

* Add %T to error output.

R.B. Boyer f9496dc627 sdk: add freelist tracking and ephemeral port range skipping to freeport
This should cut down on test flakiness.

Problems handled:

- If you had enough parallel test cases running, the former circular
approach to handling the port block could hand out the same port to
multiple cases before they each had a chance to bind them, leading to
one of the two tests to fail.

- The freeport library would allocate out of the ephemeral port range.
This has been corrected for Linux (which should cover CI).

- The library now waits until a formerly-in-use port is verified to be
free before putting it back into circulation.

Store primaries root in secondary after intermediate signature (#6333)
* Store primaries root in secondary after intermediate signature

This ensures that the intermediate exists within the CA root stored in raft and not just in the CA provider state. This has the very nice benefit of actually outputting the intermediate cert within the ca roots HTTP/RPC endpoints.

This change means that if signing the intermediate fails it will not set the root within raft. So far I have not come up with a reason why that is bad. The secondary CA roots watch will pull the root again and go through all the motions. So as soon as getting an intermediate CA works the root will get set.

I am not sure this is the full fix but it seems to help for me.

    Exit code: 1
    panic: interface conversion: interface {} is nil, not structs.Coordinates [recovered]
            panic: interface conversion: interface {} is nil, not structs.Coordinates

There is definitely a bug lurking, but the code seems to imply this can
only return nil on 404. The tests previously were not checking the
status code.

The underlying cause of the flake is unknown, but this should turn the
failure into a more normal test failure.

test: fix TestAgent.Start() to not segfault if the DNSServer cannot ListenAndServe (#6409)
The embedded `Server` field on a `DNSServer` is only set inside of the
`ListenAndServe` method. If that method fails for reasons like the
address being in use and is not bindable, then the `Server` field will
not be set and the overall `Agent.Start()` will fail.

This will trigger the inner loop of `TestAgent.Start()` to invoke
`ShutdownEndpoints` which will attempt to pretty print the DNS servers
using fields on that inner `Server` field. Because it was never set,
this causes a nil pointer dereference and crashes the test.

clusters and putting each successive destination in a different load
assignment priority band. For example this shows that normally requests
go to 1.2.3.4:8080 but when that fails they go to 6.7.8.9:8080:

- name: foo
  load_assignment:
    cluster_name: foo
    policy:
      overprovisioning_factor: 100000
    endpoints:
    - priority: 0
      lb_endpoints:
      - endpoint:
          address:
            socket_address:
              address: 1.2.3.4
              port_value: 8080
    - priority: 1
      lb_endpoints:
      - endpoint:
          address:
            socket_address:
              address: 6.7.8.9
              port_value: 8080

Mesh gateways route requests based solely on the SNI header tacked onto
the TLS layer. Envoy currently only lets you configure the outbound SNI
header at the cluster layer.

If you try to failover through a mesh gateway you ideally would
configure the SNI value per endpoint, but that's not possible in envoy
today.

This PR introduces a simpler way around the problem for now:

1. We identify any target of failover that will use mesh gateway mode local or
   remote and then further isolate any resolver node in the compiled discovery
   chain that has a failover destination set to one of those targets.

2. For each of these resolvers we will perform a small measurement of
   comparative healths of the endpoints that come back from the health API for the
   set of primary target and serial failover targets. We walk the list of targets
   in order and if any endpoint is healthy we return that target, otherwise we
   move on to the next target.

3. The CDS and EDS endpoints both perform the measurements in (2) for the
   affected resolver nodes.

4. For CDS this measurement selects which TLS SNI field to use for the cluster
   (note the cluster is always going to be named for the primary target)

5. For EDS this measurement selects which set of endpoints will populate the
   cluster. Priority tiered failover is ignored.

One of the big downsides to this approach to failover is that the failover
detection and correction is going to be controlled by consul rather than
deferring that entirely to the data plane as with the prior version. This also
means that we are bound to only failover using official health signals and
cannot make use of data plane signals like outlier detection to affect
failover.

In this specific scenario the lack of data plane signals is ok because the
effectiveness is already muted by the fact that the ultimate destination
endpoints will have their data plane signals scrambled when they pass through
the mesh gateway wrapper anyway so we're not losing much.

Another related fix is that we now use the endpoint health from the
underlying service, not the health of the gateway (regardless of
failover mode).

connect: simplify the compiled discovery chain data structures (#6242)
This should make them better for sending over RPC or the API.

Instead of a chain implemented explicitly like a linked list (nodes
holding pointers to other nodes) instead switch to a flat map of named
nodes with nodes linking other other nodes by name. The shipped
structure is just a map and a string to indicate which key to start
from.

Other changes:

* inline the compiler option InferDefaults as true

* introduce compiled target config to avoid needing to send back
  additional maps of Resolvers; future target-specific compiled state
  can go here

* move compiled MeshGateway out of the Resolver and into the
  TargetConfig where it makes more sense.

connect: reconcile how upstream configuration works with discovery chains (#6225)
* connect: reconcile how upstream configuration works with discovery chains

The following upstream config fields for connect sidecars sanely
integrate into discovery chain resolution:

- Destination Namespace/Datacenter: Compilation occurs locally but using
different default values for namespaces and datacenters. The xDS
clusters that are created are named as they normally would be.

- Mesh Gateway Mode (single upstream): If set this value overrides any
value computed for any resolver for the entire discovery chain. The xDS
clusters that are created may be named differently (see below).

- Mesh Gateway Mode (whole sidecar): If set this value overrides any
value computed for any resolver for the entire discovery chain. If this
is specifically overridden for a single upstream this value is ignored
in that case. The xDS clusters that are created may be named differently
(see below).

- Protocol (in opaque config): If set this value overrides the value
computed when evaluating the entire discovery chain. If the normal chain
would be TCP or if this override is set to TCP then the result is that
we explicitly disable L7 Routing and Splitting. The xDS clusters that
are created may be named differently (see below).

- Connect Timeout (in opaque config): If set this value overrides the
value for any resolver in the entire discovery chain. The xDS clusters
that are created may be named differently (see below).

If any of the above overrides affect the actual result of compiling the
discovery chain (i.e. "tcp" becomes "grpc" instead of being a no-op
override to "tcp") then the relevant parameters are hashed and provided
to the xDS layer as a prefix for use in naming the Clusters. This is to
ensure that if one Upstream discovery chain has no overrides and
tangentially needs a cluster named "api.default.XXX", and another
Upstream does have overrides for "api.default.XXX" that they won't
cross-pollinate against the operator's wishes.

  It wouldn't work anyway.

* Prevent two upstreams from being declared that use the same
  type+name+namespace+datacenter. Due to how the Upstream.Identity()

  but it should be enforced more clearly at register-time.

Fix CA Replication when ACLs are enabled (#6201)
Secondary CA initialization steps are:

• Wait until the primary will be capable of signing intermediate certs. We use serf metadata to check the versions of servers in the primary which avoids needing a token like the previous implementation that used RPCs. We require at least one alive server in the primary and the all alive servers meet the version requirement.
• Initialize the secondary CA by getting the primary to sign an intermediate

When a primary dc is configured, if no existing CA is initialized and for whatever reason we cannot initialize a secondary CA the secondary DC will remain without a CA. As soon as it can it will initialize the secondary CA by pulling the primaries roots and getting the primary to sign an intermediate.

This also fixes a segfault that can happen during leadership revocation. There was a spot in the secondaryCARootsWatch that was getting the CA Provider and executing methods on it without nil checking. Under normal circumstances it wont be nil but during leadership revocation it gets nil'ed out. Therefore there is a period of time between closing the stop chan and when the go routine is actually stopped where it could read a nil provider and cause a segfault.

Auto-encrypt meant to fallback to the default port when it wasn't provided, but it hadn't been because of an issue with the error handling. We were checking against an incomplete error value:
"missing port in address" vs "address $HOST: missing port in address"

Additionally, all RPCs to AutoEncrypt.Sign were using a.config.ServerPort, so those were updated to use ports resolved by resolveAddrs, if they are available.

The main change is that we no longer filter service instances by health,
preferring instead to render all results down into EDS endpoints in
envoy and merely label the endpoints as HEALTHY or UNHEALTHY.

When OnlyPassing is set to true we will force consul checks in a
'warning' state to render as UNHEALTHY in envoy.

Allow raft TrailingLogs to be configured. (#6186)
This fixes pathological cases where the write throughput and snapshot size are both so large that more than 10k log entries are written in the time it takes to restore the snapshot from disk. In this case followers that restart can never catch up with leader replication again and enter a loop of constantly downloading a full snapshot and restoring it only to find that snapshot is already out of date and the leader has truncated its logs so a new snapshot is sent etc.

In general if you need to adjust this, you are probably abusing Consul for purposes outside its design envelope and should reconsider your usage to reduce data size and/or write volume.
