xDS Load Balancing (#14397)
Prior to #13244, connect proxies and gateways could only be configured by an
xDS session served by the local client agent.

In an upcoming release, it will be possible to deploy a Consul service mesh
without client agents. In this model, xDS sessions will be handled by the
servers themselves, which necessitates load-balancing to prevent a single
server from receiving a disproportionate amount of load and becoming
overwhelmed.

This introduces a simple form of load-balancing where Consul will attempt to
achieve an even spread of load (xDS sessions) between all healthy servers.
It does so by implementing a concurrent session limiter (limiter.SessionLimiter)
and adjusting the limit according to autopilot state and proxy service
registrations in the catalog.

If a server is already over capacity (i.e. the session limit is lowered),
Consul will begin draining sessions to rebalance the load. This will result
in the client receiving a `RESOURCE_EXHAUSTED` status code. It is the client's
responsibility to observe this response and reconnect to a different server.

Users of the gRPC client connection brokered by the
consul-server-connection-manager library will get this for free.

The rate at which Consul will drain sessions to rebalance load is scaled
dynamically based on the number of proxies in the catalog.

freddygv 650e48624d Allow terminated peerings to be deleted
Peerings are terminated when a peer decides to delete the peering from
their end. Deleting a peering sends a termination message to the peer
and triggers them to mark the peering as terminated but does NOT delete
the peering itself. This is to prevent peerings from disappearing from
both sides just because one side deleted them.

Previously the Delete endpoint was skipping the deletion if the peering
was not marked as active. However, terminated peerings are also
inactive.

This PR makes some updates so that peerings marked as terminated can be
deleted by users.

Replace ring buffer with async version (#14314)
We need to watch for changes to peerings and update the server addresses which get served by the ring buffer.

Also, if there is an active connection for a peer, we are getting up-to-date server addresses from the replication stream and can safely ignore the token's addresses which may be stale.

freddygv c04515a844 Use proto message for each secrets write op

freddygv 60d6e28c97 Pass explicit signal with op for secrets write
Previously the updates to the peering secrets UUID table relied on
inferring what action triggered the update based on a reconciliation
against the existing secrets.

Instead we now explicitly require the operation to be given so that the
inference isn't necessary. This makes the UUID table logic easier to
reason about and fixes some related bugs.

There is also an update so that the peering secrets get handled on
snapshots/restores.

freddygv 9ca687bc7c Avoid deleting peering secret UUIDs at dialers
Dialers do not keep track of peering secret UUIDs, so they should not
attempt to clean up data from that table when their peering is deleted.

We also now keep peer server addresses when marking peerings for
deletion. Peer server addresses are used by the ShouldDial() helper
when determining whether the peering is for a dialer or an acceptor.
We need to keep this data so that peering secrets can be cleaned up
accordingly.

- If key material is configured for the gRPC port but HTTPS is not
  enabled now TLS will still be activated for the gRPC port.

- peerstream replication stream opened by the establishing-side will now
  ignore grpc.WithBlock so that TLS errors will bubble up instead of

grpc: rename public/private directories to external/internal (#13721)
Previously, public referred to gRPC services that are both exposed on
the dedicated gRPC port and have their definitions in the proto-public
directory (so were considered usable by 3rd parties). Whereas private
referred to services on the multiplexed server port that are only usable
by agents and other servers.

Now, we're splitting these definitions, such that external/internal
refers to the port and public/private refers to whether they can be used
by 3rd parties.

This is necessary because the peering replication API needs to be
exposed on the dedicated port, but is not (yet) suitable for use by 3rd
parties.

Revise possible states for a peering. (#13661)
These changes are primarily for Consul's UI, where we want to be more
specific about the state a peering is in.

- The "initial" state was renamed to pending, and no longer applies to
  peerings being established from a peering token.

- Upon request to establish a peering from a peering token, peerings
  will be set as "establishing". This will help distinguish between the
  two roles: the cluster that generates the peering token and the
  cluster that establishes the peering.

- When marked for deletion, peering state will be set to "deleting".
  This way the UI determines the deletion via the state rather than the
  "DeletedAt" field.

Daniel Upton 653b8c4f9d proxycfg: server-local config entry data sources
This is the OSS portion of enterprise PR 2056.

This commit provides server-local implementations of the proxycfg.ConfigEntry
and proxycfg.ConfigEntryList interfaces, that source data from streaming events.

It makes use of the LocalMaterializer type introduced for peering replication,
adding the necessary support for authorization.

It also adds support for "wildcard" subscriptions (within a topic) to the event
publisher, as this is needed to fetch service-resolvers for all services when
configuring mesh gateways.

Currently, events will be emitted for just the ingress-gateway, service-resolver,
and mesh config entry types, as these are the only entries required by proxycfg
— the events will be emitted on topics named IngressGateway, ServiceResolver,
and MeshConfig topics respectively.

Though these events will only be consumed "locally" for now, they can also be
consumed via the gRPC endpoint (confirmed using grpcurl) so using them from
client agents should be a case of swapping the LocalMaterializer for an
RPCMaterializer.

peering: replicate all SpiffeID values necessary for the importing side to do SAN validation (#13612)
When traversing an exported peered service, the discovery chain
evaluation at the other side may re-route the request to a variety of
endpoints. Furthermore we intend to terminate mTLS at the mesh gateway
for arriving peered traffic that is http-like (L7), so the caller needs
to know the mesh gateway's SpiffeID in that case as well.

The following new SpiffeID values will be shipped back in the peerstream
replication:

- tcp: all possible SpiffeIDs resulting from the service-resolver
        component of the exported discovery chain

- http-like: the SpiffeID of the mesh gateway

freddygv f3843809da Avoid deleting peerings marked as terminated.
When our peer deletes the peering it is locally marked as terminated.
This termination should kick off deleting all imported data, but should
not delete the peering object itself.

Keeping peerings marked as terminated acts as a signal that the action
took place.

freddygv 6453375ab2 Add leader routine to clean up peerings
Once a peering is marked for deletion a new leader routine will now
clean up all imported resources and then the peering itself.

A lot of the logic was grabbed from the namespace/partitions deferred
deletions but with a handful of simplifications:
- The rate limiting is not configurable.

- Deleting imported nodes/services/checks is done by deleting nodes with
  the Txn API. The services and checks are deleted as a side-effect.

- There is no "round rate limiter" like with namespaces and partitions.
  This is because peerings are purely local, and deleting a peering in
  the datacenter does not depend on deleting data from other DCs like
  with WAN-federated namespaces. All rate limiting is handled by the
  Raft rate limiter.

freddygv 6c8ab1bbac Fixup stream tear-down steps.
1. Fix a bug where the peering leader routine would not track all active
   peerings in the "stored" reconciliation map. This could lead to
   tearing down streams where the token was generated, since the
   ConnectedStreams() method used for reconciliation returns all streams
   and not just the ones initiated by this leader routine.

2. Fix a race where stream contexts were being canceled before
   termination messages were being processed by a peer.

   Previously the leader routine would tear down streams by canceling
   their context right after the termination message was sent. This
   context cancelation could be propagated to the server side faster
   than the termination message. Now there is a change where the
   dialing peer uses CloseSend() to signal when no more messages will
   be sent. Eventually the server peer will read an EOF after receiving
   and processing the preceding termination message.

   Using CloseSend() is actually not enough to address the issue
   mentioned, since it doesn't wait for the server peer to finish
   processing messages. Because of this now the dialing peer also reads
   from the stream until an error signals that there are no more
   messages. Receiving an EOF from our peer indicates that they
   processed the termination message and have no additional work to do.

   Given that the stream is being closed, all the messages received by
   Recv are discarded. We only check for errors to avoid importing new
   data.

freddygv cc921a9c78 Update peering state and RPC for deferred deletion
When deleting a peering we do not want to delete the peering and all
imported data in a single operation, since deleting a large amount of
data at once could overload Consul.

Instead we defer deletion of peerings so that:

1. When a peering deletion request is received via gRPC the peering is
   marked for deletion by setting the DeletedAt field.

2. A leader routine will monitor for peerings that are marked for
   deletion and kick off a throttled deletion of all imported resources
   before deleting the peering itself.

This commit mostly addresses point #1 by modifying the peering service
to mark peerings for deletion. Another key change is to add a
PeeringListDeleted state store function which can return all peerings
marked for deletion. This function is what will be watched by the
deferred deletion leader routine.

the union of all that apply.

Another update that was made was to reflect that only one

partition. This is a pre-existing constraint that gets enforced by
the Normalize() method on that config entry type.
