[OSS] gRPC call to get envoy bootstrap params (#12825)
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.

ConnectCA.Sign gRPC Endpoint (#12787)
Introduces a gRPC endpoint for signing Connect leaf certificates. It's also
the first of the public gRPC endpoints to perform leader-forwarding, so
establishes the pattern of forwarding over the multiplexed internal RPC port.

Move to using a shared EventPublisher (#12673)
Previously we had 1 EventPublisher per state.Store. When a state store was closed/abandoned such as during a consul snapshot restore, this had the behavior of force closing subscriptions for that topic and evicting event snapshots from the cache.

The intention of this commit is to keep all that behavior. To that end, the shared EventPublisher now supports the ability to refresh a topic. That will perform the force close + eviction. The FSM upon abandoning the previous state.Store will call RefreshTopic for all the topics with events generated by the state.Store.

Enable running autopilot state updates on all servers (#12617)
* Fixes a lint warning about t.Errorf not supporting %w

* Enable running autopilot on all servers

On the non-leader servers all they do is update the state and do not attempt any modifications.

* Fix the RPC conn limiting tests

Technically they were relying on racey behavior before. Now they should be reliable.

Support per-listener TLS configuration ⚙️ (#12504)
Introduces the capability to configure TLS differently for Consul's
listeners/ports (i.e. HTTPS, gRPC, and the internal multiplexed RPC
port) which is useful in scenarios where you may want the HTTPS or
gRPC interfaces to present a certificate signed by a well-known/public
CA, rather than the certificate used for internal communication which
must have a SAN in the form `server.<dc>.consul`.

Replaces a call to the state store to fetch the clusterID with the
clusterID field already available on the built-in provider.

Daniel Nephin 5a82859ee1 acl: small improvements to ACLResolver disable due to RPC error
Remove the error return, so that not handling is not reported as an
error by errcheck. It was returning the error passed as an arg
unmodified so there is no reason to return the same value that was
passed in.

Remove the term upstreams to remove any confusion with the term used in
service mesh.

Remove the AutoDisable field, and replace it with the TTL value, using 0
to indicate the setting is turned off.

Replace "not Before" with "After".

Add some test coverage to show the behaviour is still correct.

This change was made by GoLand refactor, which did most of the work for me.

tlsutil.Config already presents an excellent structure for this

Instead of copying the fields around, use the tlsutil.Config struct
directly instead.

This is one small step in removing the many layers of duplicate
configuration.

Ensure that CA initialization does not block leader election.
After fixing that bug I uncovered a couple more:

Fix a potential issue where reconfiguring the CA could cause either the Vault or AWS PCA CA providers to delete resources that are still required by the new incarnation of the CA.

connect: intentions are now managed as a new config entry kind "service-intentions" (#8834)
- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.

- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.

- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.

- Add a new serf feature flag indicating support for
intentions-as-config-entries.

- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.

- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.

- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.

- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.

server: ensure that we also shutdown network segment serf instances on server shutdown (#8786)
This really only matters for unit tests, since typically if an agent shuts down its server, it follows that up by exiting the process, which would also clean up all of the networking anyway.

Daniel Nephin c621b4a420 agent/consul: pass dependencies directly from agent
In an upcoming change we will need to pass a grpc.ClientConnPool from
BaseDeps into Server. While looking at that change I noticed all of the
existing consulOption fields are already on BaseDeps.

Instead of duplicating the fields, we can create a struct used by
agent/consul, and use that struct in BaseDeps. This allows us to pass
along dependencies without translating them into different
representations.

I also looked at moving all of BaseDeps in agent/consul, however that
created some circular imports. Resolving those cycles wouldn't be too
bad (it was only an error in agent/consul being imported from
cache-types), however this change seems a little better by starting to
introduce some structure to BaseDeps.

This change is also a small step in reducing the scope of Agent.

Also remove some constants that were only used by tests, and move the
relevant comment to where the live configuration is set.

Removed some validation from NewServer and NewClient, as these are not
really runtime errors. They would be code errors, which will cause a
panic anyway, so no reason to handle them specially here.

Chris Piraino 45a4057f60 Report node/service usage metrics from every server
Using the newly provided state store methods, we periodically emit usage
metrics from the servers.

We decided to emit these metrics from all servers, not just the leader,
because that means we do not have to care about leader election flapping
causing metrics turbulence, and it seems reasonable for each server to
emit its own view of the state, even if they should always converge
rapidly.

Daniel Nephin f3b63514d5 testing: Remove NotifyShutdown
NotifyShutdown was only used for testing. Now that t.Cleanup exists, we
can use that instead of attaching cleanup to the Server shutdown.

The Autopilot test which used NotifyShutdown doesn't need this
notification because Shutdown is synchronous. Waiting for the function
to return is equivalent.
