convert SA controller to shared informers
convert the SA controller to shared informer + workqueue.

PVC informer lister supports listing
This will be used in follow-on PRs for quota evaluation backed by informers for pvcs.

add optional mutation checks for shared informer cache
We need to make sure that no one is mutating caches if they're using a shared informer. It is important that whatever is tracking those changes gets the object *before* anyone else possibly could.
This adds the ability to track the original objects in the cache and their current values. Go doesn't have an exit hook or a way to say "wait for non-daemon go-funcs to complete before exit", so this runs a gofunc on a loop that can panic the entire process. It's gated behind an env var.
@derekwaynecarr did I get the right spots to make sure that e2e runs with this flag?

DeltaFIFO should not report HasSynced until deletes are reported
Deletions identified by knownObjects on the initial sync replace
(immediately after the List from a reflector) should be considered part
of the initial sync since we have the information available at the time
we do the deletion.
An error during Replace() can result in Populated not being set, but it
was incorrect before (population would be wrong) and queueActionLocked
does not error except on "my cache is broken because I gave an incorrect
keyFunc".
@lavalamp @deads2k hit this while trying to use DeltaFIFO to implement an "external" controller (one that uses the knownObjects as provided by a call to a remote system of record).

1. When overlapping deployments are discovered, annotate them
2. Expose those overlapping annotations as warnings in kubectl describe
3. Only respect the earliest updated one (skip syncing all other overlapping deployments)
4. Use indexer instead of store for deployment lister

Followup to #30839.
I'm not convinced this is a super great idea but I'll throw it out and let others decide.
