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

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.

**What this PR does / why we need it**:
The sample-controller makes extensive use of various mechanisms
available in the client-go library. For writing custom controllers/operators
it will be helpful if there is precise description of how the
client-go library works and how/where it interfaces with
custom controller code.
This patch adds documentation that sheds light on how (parts) of the
client-go library work and its interaction-points with
controller code. The documentation and the diagram comes from [1],
(link included here for reference purpose).
