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.
```
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.

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.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:

**Special notes for your reviewer**:
**Release note**:

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.

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

apiserver: Fail if dry-run query param is specified
Adds a dry-run query parameter now that does nothing but reject the request. The sooner we have this check in master, the safer it will be for clients to send dry-run requests that are not going to be applied nonetheless.
```release-note
Create a new `dryRun` query parameter for mutating endpoints. If the parameter is set, then the query will be rejected, as the feature is not implemented yet. This will allow forward compatibility with future clients; otherwise, future clients talking with older apiservers might end up modifying a resource even if they include the `dryRun` query parameter.

apiextensions: allow "required" at root with status subresource
In the subresources alpha we intentionally disallowed anything than `properties` at the root of the validation schema in order to allow us to project it to the .status subtree. By doing this we also disallowed `required` at the root which is necessary to enforce e.g. a spec to be set. This PR fixes this.
Moreover, it fixes that the restriction is only enforced when the status subresource is actually enabled. Before this PR we were enforcing the restriction as soon as the feature gate was enabled, leading to a backwards incompatible change.
```release-note
Allow "required" to be used at the CRD OpenAPI validation schema when the /status subresource is enabled.
