freddygv 0d61aa5d37 Update xds generation for peering over mesh gws
This commit adds the xDS resources needed for INBOUND traffic from peer
clusters:

- 1 filter chain for all inbound peering requests.
- 1 cluster for all inbound peering requests.
- 1 endpoint per voting server with the gRPC TLS port configured.

There is one filter chain and cluster because unlike with WAN
federation, peer clusters will not attempt to dial individual servers.
Peer clusters will only dial the local mesh gateway addresses.

freddygv 520507232f Manage local server watches depending on mesh cfg
Routing peering control plane traffic through mesh gateways can be
enabled or disabled at runtime with the mesh config entry.

This commit updates proxycfg to add or cancel watches for local servers
depending on this central config.

Note that WAN federation over mesh gateways is determined by a service
metadata flag, and any updates to the gateway service registration will
force the creation of a new snapshot. If enabled, WAN-fed over mesh
gateways will trigger a local server watch on initialize().

Because of this we will only add/remove server watches if WAN federation
over mesh gateways is disabled.

Daniel Upton 4b76d8a8ff proxycfg-glue: server-local implementation of InternalServiceDump
This is the OSS portion of enterprise PR 2489.

This PR introduces a server-local implementation of the
proxycfg.InternalServiceDump interface that sources data from a blocking query
against the server's state store.

For simplicity, it only implements the subset of the Internal.ServiceDump RPC
handler actually used by proxycfg - as such the result type has been changed
to IndexedCheckServiceNodes to avoid confusion.

xds: mesh gateways now correctly load up peer-exported discovery chains using L7 protocols (#13624)
A mesh gateway will now configure the filter chains for L7 exported
services using the correct discovery chain information.

xds: mesh gateways now have their own leaf certificate when involved in a peering (#13460)
This is only configured in xDS when a service with an L7 protocol is
exported.

They also load any relevant trust bundles for the peered services to
eventually use for L7 SPIFFE validation during mTLS termination.

peering: allow mesh gateways to proxy L4 peered traffic (#13339)
Mesh gateways will now enable tcp connections with SNI names including peering information so that those connections may be proxied.

Note: this does not change the callers to use these mesh gateways.

proxycfg: replace direct agent cache usage with interfaces (#13320)
This is the OSS portion of enterprise PRs 1904, 1905, 1906, 1907, 1949,
and 1971.

It replaces the proxycfg manager's direct dependency on the agent cache
with interfaces that will be implemented differently when serving xDS
sessions from a Consul server.

proxycfg: remove dependency on `cache.UpdateEvent` (#13144)
OSS portion of enterprise PR 1857.

This removes (most) references to the `cache.UpdateEvent` type in the
`proxycfg` package.

As we're going to be direct usage of the agent cache with interfaces that
can be satisfied by alternative server-local datasources, it doesn't make
sense to depend on this type everywhere anymore (particularly on the
`state.ch` channel).

We also plan to extract `proxycfg` out of Consul into a shared library in
the future, which would require removing this dependency.

Aside from a fairly rote find-and-replace, the main change is that the
`cache.Cache` and `health.Client` types now accept a callback function
parameter, rather than a `chan<- cache.UpdateEvents`. This allows us to
do the type conversion without running another goroutine.

freddygv f3f15640a9 Update mesh gateway proxy watches for partitions
This commit updates mesh gateway watches for cross-partitions
communication.

* Mesh gateways are keyed by partition and datacenter.

* Mesh gateways will now watch gateways in partitions that export
services to their partition.

* Mesh gateways in non-default partitions will not have cross-datacenter
watches. They are not involved in traditional WAN federation.

Daniel Nephin 1bc07c5166 structs: rename the last helper method.
This one gets used a bunch, but we can rename it to make the behaviour more obvious.

Daniel Nephin 41bf0670a8 proxycfg: move each handler into a seprate file
There is no interaction between these handlers, so splitting them into separate files
makes it easier to discover the full implementation of each kindHandler.
