Support parallel scaling on StatefulSets
Fixes#41255
```release-note
StatefulSets now include an alpha scaling feature accessible by setting the `spec.podManagementPolicy` field to `Parallel`. The controller will not wait for pods to be ready before adding the other pods, and will replace deleted pods as needed. Since parallel scaling creates pods out of order, you cannot depend on predictable membership changes within your set.

LocalStorage api
**What this PR does / why we need it**:
API changes to support persistent local volumes, as described [here](https://github.com/kubernetes/community/pull/306)
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
Part of #43640
**Special notes for your reviewer**:
There were a few items I was concerned about. Will add review comments in those places.
**Release note**:

Note will be added in subsequent PR with the volume plugin changes
Remove kubectl's dependence on pkg/api/helper, as part of
broader effort to isolate kubectl from the rest of k8s.
In this case, the code becomes private to kubectl; nobody else uses it.
**Which issue this PR fixes**
Part of a series of PRs to address kubernetes/community#598
**Special notes for your reviewer**:
**Release note**:
```release-note
NONE
```
Includes:
- A new volume type, LocalVolumeSource. This only supports
file-based local volumes for now.
- New alpha annotation in PV: NodeAffinity
- Validation + tests for specifying LocalVolumeSource and PV
NodeAffinity
- Alpha feature gate
The alpha field podManagementPolicy defines how pods are created,
deleted, and replaced. The new `Parallel` policy will replace pods
as fast as possible, not waiting for the pod to be `Ready` or providing
an order. This allows for advanced clustered software to take advantage
of rapid changes in scale.

NodeRestriction admission plugin
Adds an optional `NodeRestriction` admission plugin that limits identifiable kubelets to mutating their own Node object, and Pod objects bound to their node.
This is the admission portion of https://github.com/kubernetes/community/blob/master/contributors/design-proposals/kubelet-authorizer.md and kubernetes/features#279
```release-note
The `NodeRestriction` admission plugin limits the `Node` and `Pod` objects a kubelet can modify. In order to be limited by this admission plugin, kubelets must use credentials in the `system:nodes` group, with a username in the form `system:node:<nodeName>`. Such kubelets will only be allowed to modify their own `Node` API object, and only modify `Pod` API objects that are bound to their node.

Apiregistration v1alpha1→v1beta1
Promoting apiregistration api from v1alpha1 to v1beta1.
API Registration is responsible for registering an API `Group`/`Version` with
another kubernetes like API server. The `APIService` holds information
about the other API server in `APIServiceSpec` type as well as general
`TypeMeta` and `ObjectMeta`. The `APIServiceSpec` type have the main
configuration needed to do the aggregation. Any request coming for
specified `Group`/`Version` will be directed to the service defined by
`ServiceReference` (on port 443) after validating the target using provided
`CABundle` or skipping validation if development flag `InsecureSkipTLSVerify`
is set. `Priority` is controlling the order of this API group in the overall
discovery document.
The return status is a set of conditions for this aggregation. Currently
there is only one condition named "Available", if true, it means the
api/server requests will be redirected to specified API server.
```release-note
API Registration is now in beta.

Update 'More info' links on API types and fields
> **Please just review the first commit, the rest is generated files.**
Recent docs website shuffling during 1.6 caused majority of links in the API
types and fields to break. Since we do not have server-side 301 redirects, user
has to click an extra link, and the #target fragment in the URL will be lost. (This is
because GitHub’s redirect_from feature is not ideal.)
For the time being, I have manually gone through all of them to bring them up to date
and add HTTPS to those missing it. This is a docs-only change and impacts generated
code, generated swaggers, API reference docs etc.
cc: @steveperry-53 @devin-donnelly @chenopis fyi, docs links changes (even small title changes) easily breaks links in API reference, Swagger, kubectl explain, and many other places.

Tighten validation of mirror pod annotations
Tightens validation for pods with a mirror pod annotation:
1. spec.nodeName must be set
2. makes the mirror pod annotation immutable
3. starts validating pod-specific annotations during pod status update
None of these changes affect usage of the mirror pod annotation by kubelets, which only set it on pod creation (verified this is true back to 1.5.x)
the second commit updates the pod validation tests to look for specific error messages (best reviewed ignoring whitespace changes)
This is the validation portion of https://github.com/kubernetes/community/blob/master/contributors/design-proposals/kubelet-authorizer.md and https://github.com/kubernetes/features/issues/279
```release-note
Mirror pods must now indicate the nodeName they are bound to on creation. The mirror pod annotation is now treated as immutable and cannot be added to an existing pod, removed from a pod, or modified.

Refine ESIPP validation logic in validation.go
Separated from #41162.
The previous ESIPP validation logic in validation.go has a huge overlap with [function healthCheckNodePortUpdate in service/rest.go](870585e8e1/pkg/registry/core/service/rest.go (L283-L373)), in which we reject any invalid modifications on ESIPP annotations.
This PR removes the overlap, and make validation.go only check if values are legal and whether user mixes different API versions (alpha & beta).
We are indeed removing the alpha annotation support, but it is kept in the codes for the ease of transiting the same logic onto beta/GA.

Admission plugin to merge pod and namespace tolerations for restricting pod placement on nodes
```release-note
This admission plugin checks for tolerations on the pod being admitted and its namespace, and verifies if there is any conflict. If there is no conflict, then it merges the pod's namespace tolerations with the the pod's tolerations and it verifies them against its namespace' whitelist of tolerations and returns. If a namespace does not have its default or whitelist tolerations specified, then cluster level default and whitelist is used. An example of its versioned config:
apiVersion: apiserver.k8s.io/v1alpha1
kind: AdmissionConfiguration
plugins:
- name: "PodTolerationRestriction"
configuration:
apiVersion: podtolerationrestriction.admission.k8s.io/v1alpha1
kind: Configuration
default:
- Key: key1
Value: value1
- Key: key2

Add Host field to TCPSocketAction
Currently, TCPSocketAction always uses Pod's IP in connection. But when a pod uses the host network, sometimes firewall rules may prevent kubelet from connecting through the Pod's IP.
This PR introduces the 'Host' field for TCPSocketAction, and if it is set to non-empty string, the probe will be performed on the configured host rather than the Pod's IP. This gives users an opportunity to explicitly specify 'localhost' as the target for the above situations.

```
The reason for this error is that the input to admission plugins is internal api objects not versioned objects so expecting versioned object is incorrect. Due to this, no pod got desired tolerations and it always showed:
```
Tolerations: <none>
```
After this fix, the correct tolerations are being assigned to pods as follows:
```
Tolerations: node.alpha.kubernetes.io/notReady=:Exists:NoExecute for 300s
node.alpha.kubernetes.io/unreachable=:Exists:NoExecute for 300s

**Release note**:
```
Enable additional, custom mount options to be passed to PersistentVolume objects via volume.beta.kubernetes.io/mount-options annotation.
```
Introduced chages:
1. Re-writing of the resolv.conf file generated by docker.
Cluster dns settings aren't passed anymore to docker api in all cases, not only for pods with host network:
the resolver conf will be overwritten after infra-container creation to override docker's behaviour.
2. Added new one dnsPolicy - 'ClusterFirstWithHostNet', so now there are:
- ClusterFirstWithHostNet - use dns settings in all cases, i.e. with hostNet=true as well
- ClusterFirst - use dns settings unless hostNetwork is true
- Default

Fix azure file secret reference
Follow up to https://github.com/kubernetes/kubernetes/pull/41957
Fixes nil dereference getting secret name from AzureFile volume source.
Adds unit tests to make sure all secret references are extracted correctly, and adds reflective tests to help catch drift if new secret references are added to the pod spec

Reserve kubernetes.io and k8s.io namespace for flex volume options
Split from https://github.com/kubernetes/kubernetes/pull/39488.
Flex volume already stuffs system information into the options map, and assumes it is free to do so:
```
optionFSType = "kubernetes.io/fsType"
optionReadWrite = "kubernetes.io/readwrite"
optionKeySecret = "kubernetes.io/secret"
```
this formalizes that by reserving the `kubernetes.io` and `k8s.io` namespaces so that user-specified options are never stomped by the system, and flex plugins can know that options with those namespaces came from the system, not user-options.
```release-note
Parameter keys in a StorageClass `parameters` map may not use the `kubernetes.io` or `k8s.io` namespaces.

Guaranteed admission for Critical Pods
This is the first step in implementing node-level preemption for critical pods.
It defines the AdmissionFailureHandler interface, which allows callers, like the kubelet, to define how failed predicates are handled, and take steps to correct failures if necessary.
In the kubelet's implementation, it triggers preemption if the pod being admitted is critical, and if the only failed predicates are InsufficientResourceErrors, then it prempts (not yet implemented) other other pods to allow admission of the critical pod.

Use consistent helper for getting secret names from pod
Kubelet secret-manager and mirror-pod admission both need to know what secrets a pod spec references. Eventually, a node authorizer will also need to know the list of secrets.
This creates a single (well, double, because api versions) helper that can be used to traverse the secret names referenced from a pod, optionally short-circuiting (for places that are just looking to see if any secrets are referenced, like admission, or are looking for a particular secret ref, like authorization)
Fixes:
* secret manager not handling secrets used by env/envFrom in initcontainers
* admission allowing mirror pods with secret references

Refactor printers and describers into their own package.
This sets the stage for using printer code from the server side (decoupled from kubectl) and loosens the coupling between kubectl and the printers. `pkg/printers` contains interfaces and has an import restriction against pulling in API specific code, while `pkg/printers/internalversion` can be used for internal types.
Add a method on `Factory` for retrieving PrinterForCommand which uses the Scheme and RESTMapper from the Factory, not the hardcoded ones. This further separates kubectl from the core API scheme and allows better composition.
Change NamePrinter to use RESTMapper (previously it was hardcoding those conversions). This means that we now return plural resource names (`pods/foo`) but is correct once aliases and shortnames start being returned by the mapper.
This is a prerequisite for server side get, but is pure refactor (contains no new features).

add InternalDNS/ExternalDNS node address types
This PR adds internal/external DNS names to the types of NodeAddresses that can be reported by the kubelet.
will spawn follow up issues for cloud provider owners to include these when possible
```release-note
Nodes can now report two additional address types in their status: InternalDNS and ExternalDNS. The apiserver can use `--kubelet-preferred-address-types` to give priority to the type of address it uses to reach nodes.

Convert HPA controller to support HPA v2 mechanics
This PR converts the HPA controller to support the mechanics from HPA v2.
The HPA controller continues to make use of the HPA v1 client, but utilizes
the conversion logic to work with autoscaling/v2alpha1 objects internally.
It is the follow-up PR to #36033 and part of kubernetes/features#117.
**Release note**:
```release-note
NONE
```
There was a bug in the HPA v1 conversion logic that would occur when
a custom metric and a metric that was encoded in v1 as
targetCPUUtilizationPercentage were used at the same time. In this
case, the custom metric could overwrite the CPU metric, or vice versa.
This fixes that bug, and ensures that the fuzzer tests round-tripping
with multiple metrics.
