Kubelet config: Validate new config against future feature gates
This fixes an issue with KubeletConfiguration validation, where the
feature gates set by the new config were not taken into account.
Also fixes a validation issue with dynamic Kubelet config, where flag
precedence was not enforced prior to dynamic config validation in the
controller; this prevented rejection of dynamic configs that don't merge
well with values set via legacy flags.
Fixes#63305

Sort API Services by Kube-Version order
Sort API services based on kube-version format. If the version does not have kube-version format.
kube-version format: `v[MajorVersion]((alpha|beta)[minorVersion])?`
e.g. v1alpha1, v4, v21beta12
Sort base on:
Version type first: GA>Beta>Alpha
Major version then Minor version (if exists).
```release-note
APIServices with kube-like versions (e.g. v1, v2beta1, etc.) will be sorted appropriately within each group.
```

Client-go raises error on duplicated name in kubeconfig
(for NamedCluster, NamedContext, NamedUser, NamedExtension)
**What this PR does / why we need it**:
Client should detect duplicated name when loading `name-value` based lists in kubeconfig: `users`, `clusters`, `contexts`. Currently if there are multiple value with same name, `client-python` will pick the first one, while `client-go` will pick the last.

ref: kubernetes-client/python#445, kubernetes-client/python-base#47
**Special notes for your reviewer**:
**Release note**:
```release-note
kubectl and client-go now detects duplicated name for user, cluster and context when loading kubeconfig and reports error
```

apiextensions: promote CustomResourcesSubresources to beta
Fixes#62786
This PR promotes the CustomResourcesSubResources feature to beta and makes it enabled by default.
**Release note**:
```release-note
Subresources for custom resources is now beta and enabled by default. With this, updates to the `/status` subresource will disallow updates to all fields other than `.status` (not just `.spec` and `.metadata` as before). Also, `required` can be used at the root of the CRD OpenAPI validation schema when the `/status` subresource is enabled.

Add InstallPathHandler which allows for more then one path to be associated with health checking.
Currently it is only possible to have one group of checks which must all pass for the handler to report success.
Allowing multiple paths for these checks allows use of the same machinery for other kinds of checks, i.e. readiness.

Allow for listing & watching individual secrets from nodes
This PR:
- propagates value of `metadata.name` field from fieldSelector to `name` field in RequestInfo (for list and watch requests)
- authorizes list/watch for requests for single secrets/configmaps coming from nodes
As an example:
```
/api/v1/secrets/namespaces/ns?fieldSelector=metadata.name=foo =>
requestInfo.Name = "foo",
requestInfo.Verb = "list"
/api/v1/secrets/namespaces/ns?fieldSelector=metadata.name=foo&watch=true =>
requestInfo.Name = "foo",
requestInfo.Verb = "list"
```
```release-note
list/watch API requests with a fieldSelector that specifies `metadata.name` can now be authorized as requests for an individual named resource
```
