Setting the default image for GKE tests to Container_VM.

The purpose is to keep the current state of tests as is even if GKE changes the base image.

Fix elasticsearch cluster logging e2e test on GCI
Fix#33126Fix#32804
Additional timeouts are proven unnecessary, the problem lies with the cpu limits
The default core_pattern pipes the core dumps to /sbin/crash_reporter
which is more restrictive in saving crash dumps. So for
now, set a generic core_pattern that users can work with.
Resources are currently filtered (in order to prevent printing) at print
time in their HumanReadablePrinter handlers. This design makes it not
possible to filter objects when they are printed using any other
printer, such as YAML, JSON, or the NamePrinter.
This patch removes any filters previously added at the printer level for
pods and adds a way to define resource-specific filters before they are
sent to a printer handler. A woking filter handler for pods has also
been
implemented.
Filters affect resources being printed through the HumanReadablePrinter,
YAML, JSON, and `--template` printers.

Behave gracefully in kubectl if /version returns 404
Fixes https://github.com/kubernetes/kubernetes/issues/32679.
It's only about caching the swagger spec here. So it's safe to fall back to non-caching mode and continue.

simplify RC and SVC listers
Make the RC and SVC listers use the common list functions that more closely match client APIs, are consistent with other listers, and avoid unnecessary copies.

Fix possible panic in PodAffinityChecker
In `PodAffinityChecker.getMatchingAntiAffinityTerms()` `affinity.PodAntiAffinity` can be `nil` in this place. This problem occurs e.g. when `nil` is passed as `meta` to `PodAffinityChecker.InterPodAffinityMatches()`.
Stumbled upon it while working on #31136 (someone PTAL at that PR too, I've submitted it a month ago and seemingly no one noticed it), kube-controller-manager was crashing there.

compensate for raft/cache delay in namespace admission
When attempting to create an object in a just-created namespace, the admission plugin can reject the creation attempt for two reasons:
1. The cache of existing namespaces has not observed the creation watch event yet. There was already compensation to perform a live lookup if the namespace was not found in the cache.
2. The live lookup can be performed against a non-leader in a HA etcd setup, and can return NotFound if the non-leader etcd has not observed the creation.
This PR adds a delay, then rechecks the cache before proceeding with the live lookup. This gives both the cache and the backing storage more time to observe the create, before failing the request.
This commit moves away from using a global variable for default
configuration checking, and instead exposes a method on LoadingRules to
determine whether a particular restclient.Config should be considered
"default". This allows kubectl to provide its own defaults (the same
as before, KUBERNETES_MASTER and the static localhost:8080 values) while
allowing other clients to avoid defining them.
In-cluster config defaulting is now easier to read.

Move generated openAPI specs out of genericapiserver and make it configurable
A follow up to #31468
Generated OpenAPI Spec does not belong to genericapiserver package. A new package "generated" created in hope of all generated codes goes into it in future. Openapi folder of that package contains generated definitions and generic API server will accept the definition map as a configuration parameter.

stop etcd watcher when watch chan is closed
When startWatching() stops due to the watch chan is closed, the watcher could still keeps running in the background. When this case happen, we should stop the watcher entirely and close ResultChan() too.

Only approve evictions when budgets would stay enforced after.
Prior to this, we would approve eviction as long as the current state of
the pods matched the budget. The new version requires that after the
eviction, the pods would still match the budget.
Also update tests to match.

Fix the properties file for node e2e cri validation.
I fixed this locally before, but accidentally missed in the PR. Sorry about that.
This time, I've tried myself, it should work.
