Daniel Upton 13c04a13af proxycfg: terminate stream on irrecoverable errors
This is the OSS portion of enterprise PR 2339.

It improves our handling of "irrecoverable" errors in proxycfg data sources.

The canonical example of this is what happens when the ACL token presented by
Envoy is deleted/revoked. Previously, the stream would get "stuck" until the
xDS server re-checked the token (after 5 minutes) and terminated the stream.

Materializers would also sit burning resources retrying something that could
never succeed.

Now, it is possible for data sources to mark errors as "terminal" which causes
the xDS stream to be closed immediately. Similarly, the submatview.Store will
evict materializers when it observes they have encountered such an error.

Daniel Upton a8df87f574 proxycfg-glue: server-local implementation of `ExportedPeeredServices`
This is the OSS portion of enterprise PR 2377.

Adds a server-local implementation of the proxycfg.ExportedPeeredServices
interface that sources data from a blocking query against the server's
state store.

Daniel Upton 3655802fdc proxycfg-glue: server-local implementation of `PeeredUpstreams`
This is the OSS portion of enterprise PR 2352.

It adds a server-local implementation of the proxycfg.PeeredUpstreams interface
based on a blocking query against the server's state store.

It also fixes an omission in the Virtual IP freeing logic where we were never
updating the max index (and therefore blocking queries against
VirtualIPsForAllImportedServices would not return on service deletion).

Daniel Upton 15a319dbfe proxycfg-glue: server-local implementation of `TrustBundle` and `TrustBundleList`
This is the OSS portion of enterprise PR 2250.

This PR provides server-local implementations of the proxycfg.TrustBundle and
proxycfg.TrustBundleList interfaces, based on local blocking queries.

Daniel Upton 673d02d30f proxycfg-glue: server-local implementation of the `Health` interface
This is the OSS portion of enterprise PR 2249.

This PR introduces an implementation of the proxycfg.Health interface based on a
local materialized view of the health events.

It reuses the view and request machinery from agent/rpcclient/health, which made
it super straightforward.

Daniel Upton 3c533ceea8 proxycfg-glue: server-local implementation of `ServiceList`
This is the OSS portion of enterprise PR 2242.

This PR introduces a server-local implementation of the proxycfg.ServiceList
interface, backed by streaming events and a local materializer.

Daniel Upton fbf88d3b19 proxycfg-glue: server-local compiled discovery chain data source
This is the OSS portion of enterprise PR 2236.

Daniel Upton 45886848b4 proxycfg: server-local intention upstreams data source
This is the OSS portion of enterprise PR 2157.

It builds on the local blocking query work in #13438 to implement the
proxycfg.IntentionUpstreams interface using server-local data.

Also moves the ACL filtering logic from agent/consul into the acl/filter
package so that it can be reused here.

Daniel Upton 37ccbd2826 proxycfg: server-local intentions data source
This is the OSS portion of enterprise PR 2141.

This commit provides a server-local implementation of the `proxycfg.Intentions`
interface that sources data from streaming events.

It adds events for the `service-intentions` config entry type, and then consumes
event streams (via materialized views) for the service's explicit intentions and
any applicable wildcard intentions, merging them into a single list of intentions.

An alternative approach I considered was to consume _all_ intention events (via
`SubjectWildcard`) and filter out the irrelevant ones. This would admittedly
remove some complexity in the `agent/proxycfg-glue` package but at the expense
of considerable overhead from waking potentially many thousands of connect
proxies every time any intention is updated.

Add internal endpoint to fetch peered upstream candidates from VirtualIP table (#13642)
For initial cluster peering TProxy support we consider all imported services of a partition to be potential upstreams.

We leverage the VirtualIP table because it stores plain service names (e.g. "api", not "api-sidecar-proxy").

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.

Freddy a09c776645 Update public listener with SPIFFE Validator
Envoy's SPIFFE certificate validation extension allows for us to
validate against different root certificates depending on the trust
domain of the dialing proxy.

If there are any trust bundles from peers in the config snapshot then we
use the SPIFFE validator as the validation context, rather than the
usual TrustedCA.

The injected validation config includes the local root certificates as
well.

Configure upstream TLS context with peer root certs (#13321)
For mTLS to work between two proxies in peered clusters with different root CAs,
proxies need to configure their outbound listener to use different root certificates
for validation.

Up until peering was introduced proxies would only ever use one set of root certificates
to validate all mesh traffic, both inbound and outbound. Now an upstream proxy
may have a leaf certificate signed by a CA that's different from the dialing proxy's.

This PR makes changes to proxycfg and xds so that the upstream TLS validation
uses different root certificates depending on which cluster is being dialed.

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.
