Revert 44714 manually
#44714 broke backward compatibility for old swagger spec that kubectl still uses. The decision on #47448 was to revert this change but the change was not automatically revertible. Here I semi-manually remove all references to UnixUserID and UnixGroupID and updated generated files accordingly.
Please wait for tests to pass then review that as there may still be tests that are failing.
Fixes#47448
Adding release note just because the original PR has a release note. If possible, we should remove both release notes as they cancel each other.
**Release note**: (removed by caesarxuchao)
UnixUserID and UnixGroupID is reverted back as int64 to keep backward compatibility.

validate host paths on the kubelet for backsteps
**What this PR does / why we need it**:
This PR adds validation on the kubelet to ensure the host path does not contain backsteps that could allow the volume to escape the PSP's allowed host paths. Currently, there is validation done at in API server; however, that does not account for mismatch of OS's on the kubelet vs api server.

**Release note**:
```release-note
Paths containing backsteps (for example, "../bar") are no longer allowed in hostPath volume paths, or in volumeMount subpaths

Add Local Storage Capacity Isolation API
This PR adds the new APIs to support storage capacity isolation as
described in the proposal [https://github.com/kubernetes/community/pull/306](url)
1. Add SizeLimit for emptyDir volume
2. Add scratch and overlay storage type used by container level or
node level
**Release note**:
```release-note
Alpha feature: Local volume Storage Capacity Isolation allows users to set storage limit to isolate EmptyDir volumes, container storage overlay, and also supports allocatable storage for shared root file system.
```

Improve validation of active deadline seconds
**What this PR does / why we need it**:
Improve validation of active deadline seconds to not allow it to be larger than max uint32.
If users choose a value that is too large, the conversion of that value to a duration in seconds can cause an overflow. I see no practical benefit of having a value larger than uint32 at this time.
xref: https://bugzilla.redhat.com/show_bug.cgi?id=1456156
**Release note**:
```release-note
Restrict active deadline seconds max allowed value to be maximum uint32
```
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

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.
