Kubernetes Submit Queue 16f87fe7d8 Merge pull request #40952 from dashpole/premption 
Automatic merge from submit-queue (batch tested with PRs 41994, 41969, 41997, 40952, 40576)

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.

Andy Goldstein 9d8d6ad16c Switch scheduler to use generated listers/informers 
Where possible, switch the scheduler to use generated listers and
informers. There are still some places where it probably makes more
sense to use one-off reflectors/informers (listing/watching just a
single node, listing/watching scheduled & unscheduled pods using a field
selector).

Jacob Simpson 855627e5cb Rotate the kubelet certificate when about to expire. 
Changes the kubelet so it doesn't use the cert/key files directly for
starting the TLS server. Instead the TLS server reads the cert/key from
the new CertificateManager component, which is responsible for
requesting new certificates from the Certificate Signing Request API on
the API Server.

move the discovery and dynamic clients

Moved the dynamic client, discovery client, testing/core, and testing/cache to `client-go`.  Dependencies on api groups we don't have generated clients for have dropped out, so federation, kubeadm, and imagepolicy.

Automatic merge from submit-queue

Delay deletion of pod from the API server until volumes are deleted

Depends on #37228, and will not pass tests until that PR is merged, and this is rebased.

Keeps all kubelet behavior the same, except the kubelet will not make the "Delete" call (kubeClient.Core().Pods(pod.Namespace).Delete(pod.Name, deleteOptions)) until the volumes associated with that pod are removed.  I will perform some performance testing so that we better understand the latency impact of this change.

Is kubelet_pods.go the correct file to include the "when can I delete this pod" logic?

Kubernetes Submit Queue 3f9f7471af Merge pull request #38989 from sjenning/set-qos-field 
Automatic merge from submit-queue (batch tested with PRs 39684, 39577, 38989, 39534, 39702)

Set PodStatus QOSClass field

This PR continues the work for https://github.com/kubernetes/kubernetes/pull/37968

It converts all local usage of the `qos` package class types to the new API level types (first commit) and sets the pod status QOSClass field in the at pod creation time on the API server in `PrepareForCreate` and in the kubelet in the pod status update path (second commit).  This way the pod QOS class is set even if the pod isn't scheduled yet.

Fixes #33255

Automatic merge from submit-queue

Remove GetRootContext method from VolumeHost interface

Remove the `GetRootContext` call from the `VolumeHost` interface, since Kubernetes no longer needs to know the SELinux context of the Kubelet directory.

Per #33951 and #35127.

Depends on #33663; only the last commit is relevant to this PR.
