Daniel Nephin 34c8585b29 auto-config: move autoConfigBackend impl off of Server
Most of these methods are used exclusively for the AutoConfig RPC
endpoint. This PR uses a pattern that we've used in other places as an
incremental step to reducing the scope of Server.

Daniel Nephin d4bb9fd97a ca: move provider creation into CAManager
This further decouples the CAManager from Server. It reduces the interface between them and
removes the need for the SetLogger method on providers.

Daniel Nephin 1e23d181b5 config: remove misleading UseTLS field
This field was documented as enabling TLS for outgoing RPC, but that was not the case.
All this field did was set the use_tls serf tag.

Instead of setting this field in a place far from where it is used, move the logic to where
the serf tag is set, so that the code is much more obvious.

Daniel Nephin 3c60a46376 config: remove duplicate TLSConfig fields from agent/consul.Config
tlsutil.Config already presents an excellent structure for this
configuration. Copying the runtime config fields to agent/consul.Config
makes code harder to trace, and provides no advantage.

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.

usagemetrics: add cluster members to metrics API (#10340)
This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.

Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.

Matt Keeler 7e4ea16149 Move some things around to allow for license updating via config reload
The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.

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

Fix an issue where we might try to cross sign a cert when we never had a valid root.
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.

Daniel Nephin e5320c2db6 agent/consul: make Client/Server config reloading more obvious
I believe this commit also fixes a bug. Previously RPCMaxConnsPerClient was not being re-read from the RuntimeConfig, so passing it to Server.ReloadConfig was never changing the value.

Also improve the test runtime by not doing a lot of unnecessary work.

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.

Agent Auto Config: Implement Certificate Generation (#8360)
Most of the groundwork was laid in previous PRs between adding the cert-monitor package to extracting the logic of signing certificates out of the connect_ca_endpoint.go code and into a method on the server.

This also refactors the auto-config package a bit to split things out into multiple files.
