peering: replicate expected SNI, SPIFFE, and service protocol to peers (#13218)
The importing peer will need to know what SNI and SPIFFE name
corresponds to each exported service. Additionally it will need to know
at a high level the protocol in use (L4/L7) to generate the appropriate
connection pool and local metrics.

For replicated connect synthetic entities we edit the `Connect{}` part
of a `NodeService` to have a new section:

    {
      "PeerMeta": {
        "SNI": [
          "web.default.default.owt.external.183150d5-1033-3672-c426-c29205a576b8.consul"
        ],
        "SpiffeID": [
          "spiffe://183150d5-1033-3672-c426-c29205a576b8.consul/ns/default/dc/dc1/svc/web"
        ],
        "Protocol": "tcp"
      }
    }

This data is then replicated and saved as-is at the importing side. Both
SNI and SpiffeID are slices for now until I can be sure we don't need
them for how mesh gateways will ultimately work.

acl: gRPC login and logout endpoints (#12935)
Introduces two new public gRPC endpoints (`Login` and `Logout`) and
includes refactoring of the equivalent net/rpc endpoints to enable the
majority of logic to be reused (i.e. by extracting the `Binder` and
`TokenWriter` types).

This contains the OSS portions of the following enterprise commits:

health: ensure /v1/health/service/:service endpoint returns the most recent results when a filter is used with streaming (#12640)
The primary bug here is in the streaming subsystem that makes the overall v1/health/service/:service request behave incorrectly when servicing a blocking request with a filter provided.

There is a secondary non-streaming bug being fixed here that is much less obvious related to when to update the `reply` variable in a `blockingQuery` evaluation. It is unlikely that it is triggerable in practical environments and I could not actually get the bug to manifest, but I fixed it anyway while investigating the original issue.

Simple reproduction (streaming):

1. Register a service with a tag.

        curl -sL --request PUT 'http://localhost:8500/v1/agent/service/register' \
            --header 'Content-Type: application/json' \
            --data-raw '{ "ID": "ID1", "Name": "test", "Tags":[ "a" ], "EnableTagOverride": true }'

2. Do an initial filter query that matches on the tag.

        curl -sLi --get 'http://localhost:8500/v1/health/service/test' --data-urlencode 'filter=a in Service.Tags'

3. Note you get one result. Use the `X-Consul-Index` header to establish
   a blocking query in another terminal, this should not return yet.

        curl -sLi --get 'http://localhost:8500/v1/health/service/test?index=$INDEX' --data-urlencode 'filter=a in Service.Tags'

4. Re-register that service with a different tag.

        curl -sL --request PUT 'http://localhost:8500/v1/agent/service/register' \
            --header 'Content-Type: application/json' \
            --data-raw '{ "ID": "ID1", "Name": "test", "Tags":[ "b" ], "EnableTagOverride": true }'

5. Your blocking query from (3) should return with a header
   `X-Consul-Query-Backend: streaming` and empty results if it works
   correctly `[]`.

Attempts to reproduce with non-streaming failed (where you add `&near=_agent` to the read queries and ensure `X-Consul-Query-Backend: blocking-query` shows up in the results).

catalog: compare node names case insensitively in more places (#12444)
Many places in consul already treated node names case insensitively.
The state store indexes already do it, but there are a few places that
did a direct byte comparison which have now been corrected.

One place of particular consideration is ensureCheckIfNodeMatches
which is executed during snapshot restore (among other places). If a
node check used a slightly different casing than the casing of the node
during register then the snapshot restore here would deterministically
fail. This has been fixed.

Primary approach:

    git grep -i "node.*[!=]=.*node" -- ':!*_test.go' ':!docs'
    git grep -i '\[[^]]*member[^]]*\]
    git grep -i '\[[^]]*\(member\|name\|node\)[^]]*\]' -- ':!*_test.go' ':!website' ':!ui' ':!agent/proxycfg/testing.go:' ':!*.md'

freddygv cbea3d203c Fix race of upstreams with same passthrough ip
Due to timing, a transparent proxy could have two upstreams to dial
directly with the same address.

For example:
- The orders service can dial upstreams shipping and payment directly.
- An instance of shipping at address 10.0.0.1 is deregistered.
- Payments is scaled up and scheduled to have address 10.0.0.1.
- The orders service receives the event for the new payments instance
before seeing the deregistration for the shipping instance. At this
point two upstreams have the same passthrough address and Envoy will
reject the listener configuration.

To disambiguate this commit considers the Raft index when storing
passthrough addresses. In the example above, 10.0.0.1 would only be
associated with the newer payments service instance.

freddygv 497aab669f Add a new table to query service names by kind
This table purposefully does not index by partition/namespace. It's a
global view into all service names.

This table is intended to replace the current serviceListTxn watch in
intentionTopologyTxn. For cross-partition transparent proxying we need
to be able to calculate upstreams from intentions in any partition. This
means that the existing serviceListTxn function is insufficient since
it's scoped to a partition.

Moving away from that function is also beneficial because it watches the
main "services" table, so watchers will wake up when any instance is
registered or deregistered.

Relax validation for expose.paths config (#10394)
Previously we would return an error if duplicate paths were specified.
This could lead to problems in cases where a user has the same path,

This validation was added to signal a potential misconfiguration.
Instead we will only check for duplicate listener ports, since that is
what would lead to ambiguity issues when generating xDS config.

In the future we could look into using a single listener and creating
distinct filter chains for each path/port.

Christopher Broglie f0307c73e5 Add support for configuring TLS ServerName for health checks
Some TLS servers require SNI, but the Golang HTTP client doesn't
include it in the ClientHello when connecting to an IP address. This
change adds a new TLSServerName field to health check definitions to
optionally set it. This fixes #9473.

Daniel Nephin d113f0e690 structs: Fix printing of IDs
These types are used as values (not pointers) in other structs. Using a pointer receiver causes
problems when the value is printed. fmt will not call the String method if it is passed a value
and the String method has a pointer receiver. By using a value receiver the correct string is printed.

Also remove some unused methods.

add primary keys to list keyring (#8522)
During gossip encryption key rotation it would be nice to be able to see if all nodes are using the same key. This PR adds another field to the json response from `GET v1/operator/keyring` which lists the primary keys in use per dc. That way an operator can tell when a key was successfully setup as primary key.

Based on https://github.com/hashicorp/serf/pull/611 to add primary key to list keyring output:

```json
[
  {
    "WAN": true,
    "Datacenter": "dc2",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 6,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 6
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 6
    },
    "NumNodes": 6
  },
  {
    "WAN": false,
    "Datacenter": "dc2",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 8,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "NumNodes": 8
  },
  {
    "WAN": false,
    "Datacenter": "dc1",
    "Segment": "",
    "Keys": {
      "0OuM4oC3Os18OblWiBbZUaHA7Hk+tNs/6nhNYtaNduM=": 3,
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "PrimaryKeys": {
      "SINm887hKTzmMWeBNKTJReaTLX3mBEJKriDyt88Ad+g=": 8
    },
    "NumNodes": 8
  }
]
```

I intentionally did not change the CLI output because I didn't find a good way of displaying this information. There are a couple of options that we could implement later:
* add a flag to show the primary keys
* add a flag to show json output

Fixes #3393.

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.
