Allow pods to opt out of PodPreset mutation via an annotation on the pod
An annotation in the pod spec of the form:
podpreset.admission.kubernetes.io/PodPresetOptOut: "true"
Will cause the admission controller to skip manipulating the pod spec,
no matter the labelling.
This is an alternative implementation to pull #44163.

This PR adds two features:
1. add support for isolating the emptyDir volume use. If user
sets a size limit for emptyDir volume, kubelet's eviction manager
monitors its usage
and evict the pod if the usage exceeds the limit.
2. add support for isolating the local storage for container overlay. If
the container's overly usage exceeds the limit defined in container
spec, eviction manager will evict the pod.
An annotation in the pod spec of the form:
podpreset.admission.kubernetes.io/exclude: "true"
Will cause the admission controller to skip manipulating the pod spec,
no matter the labelling.
The annotation for a podpreset acting on a pod has also been slightly
modified to contain a podpreset prefix:
podpreset.admission.kubernetes.io/podpreset-{name} = resource version
Fixes#44161

Add annotation for image policy webhook fail open.
**What this PR does / why we need it**: there's no good way to audit log if binary verification fails open. Adding an annotation can solve that, and provide a useful tool to audit [non-malicious] containers.
**Release note**: add the annotation "alpha.image-policy.k8s.io/failed-open=true" to pods created when the image policy webhook fails open.
```release-note
Add the `alpha.image-policy.k8s.io/failed-open=true` annotation when the image policy webhook encounters an error and fails open.

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.
@kubernetes/sig-api-machinery-misc @kubernetes/api-reviewers @kubernetes/api-approvers
@derekwaynecarr since most of these are related to the kubelet

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.
```

Local storage plugin
**What this PR does / why we need it**:
Volume plugin implementation for local persistent volumes. Scheduler predicate will direct already-bound PVCs to the node that the local PV is at. PVC binding still happens independently.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
Part of #43640
**Release note**:
```
Alpha feature: Local volume plugin allows local directories to be created and consumed as a Persistent Volume. These volumes have node affinity and pods will only be scheduled to the node that the volume is at.

This commit regenerates the protobuf as per the recent generation
changes (removing erroneous imports, adding k8s.io/metrics), and
syncs the changes to client-go (which also ensures that client-go
protobuf IDL has the correct package names).

clear init container status annotations when cleared in status
When I pod with an init container is terminated due to exceeding its active deadline, the pod status is phase `Failed` with reason `DeadlineExceeded`. All container statuses are cleared from the pod status.
With init containers, however, the status is being regenerated from the status annotations. This is causing kubectl to report the pod state as `Init:0/1` instead of `DeadlineExceeded` because the kubectl printer observes a running init container, which in reality is not running.
This PR clears out the init container status annotations when they have been removed from the pod status so they are not regenerated on the apiserver.

Fix init container status reporting when active deadline is exceeded.
