If we go a certain amount of time without being able to create a client
cert and we have no current client cert from the store, exit. This
prevents a corrupted local copy of the cert from leaving the Kubelet in a
zombie state forever. Exiting allows a config loop outside the Kubelet
to clean up the file or the bootstrap client cert to get another client
cert.

Add windows config to Kubelet CRI
**What this PR does / why we need it**:
Currently Container Runtime Interface (CRI) only supports LinuxContainerConfig and therefore LinuxContainerResources in ContainerConfig. Windows resource config is different from Linux's, although it shares some common properties.
This PR adds windows config to CRI. Add newly added WindowsContainerResources is original from OCI spec (see https://github.com/opencontainers/runtime-spec/blob/master/specs-go/config.go#L437).

delete duplicate function for getting volume source
**What this PR does / why we need it**:
these two methods have same function.
```go
func getVolumeSource(
spec *volume.Spec) (*v1.GlusterfsVolumeSource, bool, error) {
if spec.Volume != nil && spec.Volume.Glusterfs != nil {
return spec.Volume.Glusterfs, spec.Volume.Glusterfs.ReadOnly, nil
} else if spec.PersistentVolume != nil &&
spec.PersistentVolume.Spec.Glusterfs != nil {
return spec.PersistentVolume.Spec.Glusterfs, spec.ReadOnly, nil
}
return nil, false, fmt.Errorf("Spec does not reference a Glusterfs volume type")
}
func (plugin *glusterfsPlugin) getGlusterVolumeSource(spec *volume.Spec) (*v1.GlusterfsVolumeSource, bool) {
// Glusterfs volumes used directly in a pod have a ReadOnly flag set by the pod author.
// Glusterfs volumes used as a PersistentVolume gets the ReadOnly flag indirectly through the persistent-claim volume used to mount the PV
if spec.Volume != nil && spec.Volume.Glusterfs != nil {
return spec.Volume.Glusterfs, spec.Volume.Glusterfs.ReadOnly
}
return spec.PersistentVolume.Spec.Glusterfs, spec.ReadOnly
}
```
`getVolumeSource` seems to be much better.

Add NominatedNodeName field to PodStatus
**What this PR does / why we need it**:
Today, Scheduler uses an annotation called "nominated-node-name" to mark a preemptor Pod. This annotation helps scheduler know about the Pods that are destined to run on the nodes so that the resources made available by preemption is not allocated to a different Pod. In a recent discussion with @bgrant0607, we learned that we should change the annotation to a field as this field can be used by multiple schedulers and other components that may make scheduling-related decisions (descheduler, auto-scaler, kube-arbitrator, ...).

Ensure that the runtime mounts RO volumes read-only
**What this PR does / why we need it**:
This change makes it so that containers cannot write to secret, configMap, downwardAPI and projected volumes since the runtime will now mount them read-only. This change makes things less confusing for a user since any attempt to update a secret volume will result in an error rather than a successful change followed by a revert by the kubelet when the volume next syncs.
It also adds a feature gate `ReadOnlyAPIDataVolumes` to a provide a way to disable the new behavior in 1.10, but for 1.11, the new behavior will become non-optional.
Also, E2E tests for downwardAPI and projected volumes are updated to mount the volumes somewhere other than /etc.
**Which issue(s) this PR fixes**
Fixes#58719
**Release note**:
```release-note
Containers now mount secret, configMap, downwardAPI and projected volumes read-only. Previously,
container modifications to files in these types of volumes were temporary and reverted by the kubelet
during volume sync. Until version 1.11, setting the feature gate ReadOnlyAPIDataVolumes=false will
preserve the old behavior.
