Decouple xds capacity controller and autopilot
This prevents a potential bug where autopilot deadlocks while attempting
to execute `AutopilotDelegate.NotifyState()` on an xdscapacity controller
that stopped consuming messages.
* Update cache section for certain API calls
Providing more detail to the cache section to address behavior of API calls using streaming backend. This will help users understand that when '?index' is used and '?cached' is not, caching to servers will be bypassed, causing entry_fetch_max_burst and entry_fetch_rate to not be used in this scenario.
* Update website/content/docs/agent/config/config-files.mdx

* Skip collecting data directory stats in dev mode
In dev mode, the data directory is not set, so this metrics collection would
always fail and logs errors.
* Log collection errors at DEBUG level
There isn't much action a user can take to fix these errors, so
logging them as DEBUG rather than ERROR.
* Panic when controllers attempt to make invalid requests to the resource service
This will help to catch bugs in tests that could cause infinite errors to be emitted.
* Disable the API GW v2 controller
With the previous commit, this would cause a server to panic due to watching a type which has not yet been created/registered.
* Ensure that a test server gets the full type registry instead of constructing its own
* Skip TestServer_ControllerDependencies
* Fix peering tests so that they use the full resource registry.

Fix issue with persisting proxy-defaults
This resolves an issue introduced in hashicorp/consul#19829
where the proxy-defaults configuration entry with an HTTP protocol
cannot be updated after it has been persisted once and a router
exists. This occurs because the protocol field is not properly
pre-computed before being passed into validation functions.

NET-7488 - dns v2 add support for prepared queries in catalog v1 data model.
The endpoints controller currently encodes the list of unique workload identities
referenced by all workload matched by a Service into a special data-bearing
status condition on that Service. This allows a downstream controller to avoid an
expensive watch on the ServiceEndpoints type just to get this data.
The current encoding does not lend itself well to machine parsing, which is what
the field is meant for, so this PR simplifies the encoding from:
"blah blah: " + strings.Join(ids, ",") + "."
to
strings.Join(ids, ",")
It also provides an exported utility function to easily extract this data.
The new controller caches are initialized before the DependencyMappers or the
Reconciler run, but importantly they are not populated. The expectation is that
when the WatchList call is made to the resource service it will send an initial
snapshot of all resources matching a single type, and then perpetually send
UPSERT/DELETE events afterward. This initial snapshot will cycle through the
caching layer and will catch it up to reflect the stored data.
Critically the dependency mappers and reconcilers will race against the restoration
of the caches on server startup or leader election. During this time it is possible a
mapper or reconciler will use the cache to lookup a specific relationship and
not find it. That very same reconciler may choose to then recompute some
persisted resource and in effect rewind it to a prior computed state.
Change
- Since we are updating the behavior of the WatchList RPC, it was aligned to
match that of pbsubscribe and pbpeerstream using a protobuf oneof instead of the enum+fields option.
- The WatchList rpc now has 3 alternating response events: Upsert, Delete,
EndOfSnapshot. When set the initial batch of "snapshot" Upserts sent on a new
watch, those operations will be followed by an EndOfSnapshot event before beginning
the never-ending sequence of Upsert/Delete events.
- Within the Controller startup code we will launch N+1 goroutines to execute WatchList
queries for the watched types. The UPSERTs will be applied to the nascent cache
only (no mappers will execute).
- Upon witnessing the END operation, those goroutines will terminate.
- When all cache priming routines complete, then the normal set of N+1 long lived
watch routines will launch to officially witness all events in the system using the
primed cached.
* Trigger the v1 compat exported-services controller when the v1 config entry is modified.
* Hook up exported-services config entries to the event publisher.
* Add tests to the v2 exported services shim.
* Use the local materializer trigger updates on the v1 compat exported services controller when exported-services config entries are modified.
* stop sleeping when context is cancelled
This fixes behavior introduced by hashicorp/consul#20232 where
a function was added to the iptables configuration struct. Since this
struct is actually marshalled into json by consul-k8s, we should not be
placing functions inside of it.
* Convert consul-hcp to a simpler component
* update existing test to use envStub helper
* An hcp link item for the navbar
* A method of linking to HCP
* Hook up fetching linking status to the nav-item
* Hooking up fetching link status to the hcp link friend
* Adding some tests
* remove a comment - but also fix padding justify-content
* Fix the banner tests
* Adding permission tests as well
* some more sane formatting
* Rename function with its now multipurpose use
* Feature change: No more NEW Badge since it breaks padding - instead a linked badge
* Removing unused class
* Add validation of MeshGateway name + listeners
* Adds test for ValidateMeshGateway
* Fixes data fetcher test for gatewayproxy
