R.B. Boyer 6a39b47448 Support Incremental xDS mode (#9855)
This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged.

Union of all commit messages follows to give an overarching summary:

xds: exclusively support incremental xDS when using xDS v3

Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail.
Work around a strange older envoy behavior involving empty CDS responses over incremental xDS.
xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support

Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead.
Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client.
xds: pull out checkStreamACLs method in advance of a later commit

xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings

In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty.

This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10.

xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time

Add flags to consul connect envoy for metrics merging. (#9768)
Allows setting -prometheus-backend-port to configure the cluster
envoy_prometheus_bind_addr points to.

Allows setting -prometheus-scrape-path to configure which path
envoy_prometheus_bind_addr exposes metrics on.

-prometheus-backend-port is used by the consul-k8s metrics merging feature, to
configure envoy_prometheus_bind_addr to point to the merged metrics
endpoint that combines Envoy and service metrics so that one set of
annotations on a Pod can scrape metrics from the service and it's Envoy
sidecar.

-prometheus-scrape-path is used to allow configurability of the path
where prometheus metrics are exposed on envoy_prometheus_bind_addr.

xds: remove deprecated usages of xDS (#9602)
Note that this does NOT upgrade to xDS v3. That will come in a future PR.

Additionally:

- Ignored staticcheck warnings about how github.com/golang/protobuf is deprecated.
- Shuffled some agent/xds imports in advance of a later xDS v3 upgrade.
- Remove support for envoy 1.13.x but don't add in 1.17.x yet. We have to wait until the xDS v3 support is added in a follow-up PR.

xds: revert setting set_node_on_first_message_only to true when generating envoy bootstrap config (#8440)
When consul is restarted and an envoy that had already sent
DiscoveryRequests to the previous consul process sends a request to the
new process it doesn't respect the setting and never populates
DiscoveryRequest.Node for the life of the new consul process due to this
bug: https://github.com/envoyproxy/envoy/issues/9682

Fix envoy bootstrap logic to not append multiple self_admin clusters (#8371)
Previously, the envoy bootstrap config would blindly copy the self_admin
cluster into the list of static clusters when configuring either
ReadyBindAddr, PrometheusBindAddr, or StatsBindAddr.

Since ingress gateways always configure the ReadyBindAddr property,
users ran into this case much more often than previously.

Daniel Nephin 0888c6575b Step 3: fix a bug in api.NewClient and fix the tests
The api client should never rever to HTTP if the user explicitly

an non-TLS http server, but some tests explicitly enable TLS.

Daniel Nephin 1a8ffec6a7 Step 2: extract the grpc address logic and a new type
The new grpcAddress function contains all of the logic to translate the
command line options into the values used in the template.

The new type has two advantages.

1. It introduces a logical grouping of values in the BootstrapTplArgs
   struct which is exceptionally large. This grouping makes the struct
   easier to understand because each set of nested values can be seen
   as a single entity.
2. It gives us a reasonable return value for this new function.

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.
