apimachinery: adapt ObjectConvertor invariant
We avoid deepcopies in the codec/conversion stack by re-using data structures. This means that the out object of a conversion must be deepcopied before mutation in order to not mutate the in object as well.
This guarantees that e.g. runtime.Encode (which uses conversion from internal -> versioned) does not mutate the input. This would be highly unexpected (and we do not mention possible mutation of the input for runtime.Encode).

Openapi some cleanup
Clean-up some OpenAPI code, mostly test related (there are two implementations of "Fake").
This is going for master, but I'll probably also cherry-pick/create a similar PR for feature-serverside-apply branch since we'll need that to move some code around.

kubeadm: Refactor the Bootstrap Tokens usage in the API types
**What this PR does / why we need it**:
This PR:
- Moves some common, generic Bootstrap Token helpers and constants from `k8s.io/kubernetes/cmd/kubeadm/app/util/token` to `k8s.io/client-go/tools/bootstrap/token/`
- Breaks out the top-level Bootstrap Token fields to a dedicated `BootstrapToken` struct with helper functions.
- Instead of representing the Bootstrap Token as a plain `string`, there is now a wrapper struct `BootstrapTokenString` that can marshal/unmarshal correctly and supports validation on create, and splitting up the full token in the ID/Secret parts automatically.
- Makes kubeadm support multiple Bootstrap Tokens automatically by supporting a slice of `BootstrapToken` in the `MasterConfiguration` API object
- Consolidates the place for kubeadm to create token-related flags in an `options` package
- Supports automatic conversion from the `v1alpha1` to `v1alpha2` API
- Adds support to set token expiration directly instead of setting a TTL (Expiration and TTL are mutually exclusive)
- Removes the old `TokenDiscovery` struct we're not using anymore inside of kubeadm

**Special notes for your reviewer**:
This is work in progress. Please only review the first two commits for now.
I will work on splitting up this PR in smaller chunks.
I will also write unit tests tomorrow.
**Release note**:
```release-note
[action required] kubeadm: The Token-related fields in the `MasterConfiguration` object have now been refactored. Instead of the top-level `.Token`, `.TokenTTL`, `.TokenUsages`, `.TokenGroups` fields, there is now a `BootstrapTokens` slice of `BootstrapToken` objects that support the same features under the `.Token`, `.TTL`, `.Usages`, `.Groups` fields.

core v1: deprecate the gitRepo volume type
gitRepo stopped accepting new features nearly 2 years ago https://github.com/kubernetes/kubernetes/issues/17676#issuecomment-228650586 and today this behavior can easily be achieved through an init container. The kubelet shelling out to git in the host namespace can also be a security issue on un-trusted repos, as was demonstrated by [CVE-2017-1000117](https://groups.google.com/forum/#!topic/kubernetes-announce/CTLXJ74cu8M). Our own documentation even alludes to this volume type being removed in the future:
> In the future, such volumes may be moved to an even more decoupled model, rather than extending the Kubernetes API for every such use case.
https://kubernetes.io/docs/concepts/storage/volumes/#gitrepo
Closes https://github.com/kubernetes/kubernetes/issues/60999
```release-note-action-required
The GitRepo volume type is deprecated. To provision a container with a git repo, mount an EmptyDir into an InitContainer that clones the repo using git, then mount the EmptyDir into the Pod's container.

**Special notes for your reviewer**:
This pull request only adds to the help message the possible values of the TLS Cipher suites for Kubelet and api server.
It is an addition to the already merged PR https://github.com/kubernetes/kubernetes/pull/48859
The help output looks like this:
```
--tls-cert-file string File containing the default x509 Certificate for HTTPS. (CA cert, if any, concatenated after server cert). If HTTPS serving is enabled, and --tls-cert-file and --tls-private-key-file are not provided, a self-signed certificate and key are generated for the public address and saved to the directory specified by --cert-dir.
--tls-cipher-suites strings Comma-separated list of cipher suites for the server. Values are from tls package constants (https://golang.org/pkg/crypto/tls/#pkg-constants). If omitted, the default Go cipher suites will be use. Possible values: TLS_ECDHE_ECDSA_WITH_RC4_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_RSA_WITH_3DES_EDE_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_RC4_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
--tls-min-version string Minimum TLS version supported. Value must match version names from https://golang.org/pkg/crypto/tls/#pkg-constants.

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**:
```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.

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.

The sample-controller makes extensive use of various mechanisms

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).

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.
