Prior to this commit, all peer services were transmitted as connect-enabled
as long as a one or more mesh-gateways were healthy. With this change, there
is now a difference between typical services and connect services transmitted
via peering.
A service will be reported as "connect-enabled" as long as any of these
conditions are met:
1. a connect-proxy sidecar is registered for the service name.
2. a connect-native instance of the service is registered.
3. a service resolver / splitter / router is registered for the service name.
4. a terminating gateway has registered the service.
Contains 2 changes to the GetEnvoyBootstrapParams response to support
consul-dataplane.
Exposing node_name and node_id:
consul-dataplane will support providing either the node_id or node_name in its
configuration. Unfortunately, supporting both in the xDS meta adds a fair amount
of complexity (partly because most tables are currently indexed on node_name)
so for now we're going to return them both from the bootstrap params endpoint,
allowing consul-dataplane to exchange a node_id for a node_name (which it will
supply in the xDS meta).
Properly setting service for gateways:
To avoid the need to special case gateways in consul-dataplane, service will now
either be the destination service name for connect proxies, or the gateway
service name. This means it can be used as-is in Envoy configuration (i.e. as a
cluster name or in metric tags).
1. Create a bexpr filter for performing the filtering
2. Change the state store functions to return the raw (not aggregated)
list of ServiceNodes.
3. Move the aggregate service tags by name logic out of the state store
functions into a new function called from the RPC endpoint
4. Perform the filtering in the endpoint before aggregation.
Adds fine-grained node.[node] entries to the index table, allowing blocking queries to return fine-grained indexes that prevent them from returning immediately when unrelated nodes/services are updated.

OSS port of enterprise PR 1822
Includes the necessary changes to the `proxycfg` and `xds` packages to enable
Consul servers to configure arbitrary proxies using catalog data.
Broadly, `proxycfg.Manager` now has public methods for registering,
deregistering, and listing registered proxies — the existing local agent
state-sync behavior has been moved into a separate component that makes use of
these methods.
When an xDS session is started for a proxy service in the catalog, a goroutine
will be spawned to watch the service in the server's state store and
re-register it with the `proxycfg.Manager` whenever it is updated (and clean
it up when the client goes away).
Adds a new gRPC endpoint to get envoy bootstrap params. The new consul-dataplane service will use this
endpoint to generate an envoy bootstrap configuration.
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'

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.
Add a skip condition to all tests slower than 100ms.
This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.
See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests
With this change:
```
$ time go test -count=1 -short ./agent
ok github.com/hashicorp/consul/agent 0.743s
real 0m4.791s
$ time go test -count=1 -short ./agent/consul
ok github.com/hashicorp/consul/agent/consul 4.229s
real 0m8.769s
```
Required also converting some of the transaction functions to WriteTxn
because TxnRO() called the same helper as TxnRW.
This change allows us to return a memdb.Txn for read-only txn instead of
wrapping them with state.txn.
