Enable garbage collection of custom resources
Enhance the garbage collector to periodically refresh the resources it monitors (via discovery) to enable custom resource definition GC (addressing #44507 and reverting #47432).
This is a replacement for #46000.
/cc @lavalamp @deads2k @sttts @caesarxuchao
/ref https://github.com/kubernetes/kubernetes/pull/48065
```release-note
The garbage collector now supports custom APIs added via CustomeResourceDefinition or aggregated apiservers. Note that the garbage collector controller refreshes periodically, so there is a latency between when the API is added and when the garbage collector starts to manage it.

Use the core client with version

Enhance the garbage collector to periodically refresh the resources it
monitors (via discovery) to enable custom resource definition GC.
This implementation caches Unstructured structs for any kinds not
covered by a shared informer. The existing meta-only codec only supports
compiled types; an improved codec which supports arbitrary types could
be introduced to optimize caching to store only metadata for all
non-informer types.

Remove default binding of system:node role to system:nodes group
part of https://github.com/kubernetes/features/issues/279
deprecation of this automatic binding announced in 1.7 in https://github.com/kubernetes/kubernetes/pull/46076
```release-note
RBAC: the `system:node` role is no longer automatically granted to the `system:nodes` group in new clusters. It is recommended that nodes be authorized using the `Node` authorization mode instead. Installations that wish to continue giving all members of the `system:nodes` group the `system:node` role (which grants broad read access, including all secrets and configmaps) must create an installation-specific `ClusterRoleBinding`.

Allow nodes to create evictions for its own pods in NodeRestriction admission controller
**What this PR does / why we need it**: This PR adds support for `pods/eviction` sub-resource to the NodeRestriction admission controller so it allows a node to evict pods bound to itself.
**Which issue this PR fixes**: fixes#48666
**Special notes for your reviewer**: The NodeRestriction already allows nodes to delete pods bound to itself, so allowing nodes to also delete pods via the Eviction API probably makes sense.
```release-note
NodeRestriction allows a node to evict pods bound to itself

Add a new API version apps/v1beta2
xref: #49135
This PR adds a new API version `apps/v1beta2` which contains a copy (of types, conversions, and defaults) of `apps/v1beta1` StatefulSet, Deployment, and their subresources. Note that `apps/v1beta2` is still WIP and we will make breaking changes to it before releasing 1.8.
Moving core controllers (StatefulSet, Deployment, ReplicaSet, DaemonSet) to `apps/v1beta2` is the first step of moving them to `apps/v1` (GA).
This PR is a starting point for DaemonSet and ReplicaSet to move from `/extensions` to `/apps` and for Deployment and StatefulSet to make some breaking changes (e.g. new defaults and/or remove deprecated fields).
```release-note
Add a new API version apps/v1beta2

Add PriorityClass API object under new "scheduling" API group
**What this PR does / why we need it**: This PR is a part of a series of PRs to add pod priority to Kubernetes. This PR adds a new API group called "scheduling" with a new API object called "PriorityClass". PriorityClass maps the string value of priority to its integer value.

*: remove --insecure-allow-any-token option
~Since the authenticator is still used in e2e tests, don't remove
the actual package. Maybe a follow up?~
edit: e2e and integration tests have been switched over to the tokenfile
authenticator instead.
```release-note
The --insecure-allow-any-token flag has been removed from kube-apiserver. Users of the flag should use impersonation headers instead for debugging.

Remove old, core/v1 specific constructs from RESTClient
Now that metav1 is abstracted from the APIs, RESTClient should also be agnostic to the core API.
* Remove `LabelSelectorParam` and `FieldSelectorParam` - use `VersionedParams` with `ListOptions`
* Remove `UintParam`
* Remove all legacy field selector logic from `VersionedParams` - ParameterCodec now handles that
* Remove special parameters (like `timeout`) which is no longer set by most clients
