Skip pods that refer to PVCs that are being deleted
**What this PR does / why we need it**:
New check was added to `Schedule()` to make sure that a scheduled pod refers to existing PVCs that are not being deleted.
In 1.9 we plan to add a new feature that uses finalizers on PVC to protect PVCs that are used by a running pod from being deleted. This finalizer will be removed when all pods that use a PVC are finished or deleted. See https://github.com/kubernetes/community/blob/master/contributors/design-proposals/storage/postpone-pvc-deletion-if-used-in-a-pod.md for details.
I needed to pass `pvcLister` to `GenericScheduler`.
UX:
```
$ kubectl describe pod
...

```
**Release note**:
```release-note

httptest server should be close since Close issue has been fixed
**What this PR does / why we need it**:
per https://github.com/kubernetes/kubernetes/issues/19254, the issue seem to be fix for a long time and `server.Close` is no longer a issue in current related golang version, so it's time to uncomment the server.Close().

Create{Container,Pod}SecurityContext: modify a pod and don't return the annotations
**What this PR does / why we need it**:
Prior https://github.com/kubernetes/kubernetes/pull/52849 we couldn't modify a pod and had to return annotations from the methods. But now, as we always working with a copy of a pod, we can modify it directly and we don't need to copy&return annotations separately.
This PR simplifies the code by modifying a pod directly. Also it renames these methods and replaces returning of the `SecurityContext` by in-place modification.
In fact it reverts the changes from https://github.com/kubernetes/kubernetes/pull/30257

```release-note

Add pvc as part of equivalence hash
**What this PR does / why we need it**:
Should add PVC as part of equivalence hash so that `StatefulSe`t and `Operator` will always run the volume predicate, while the `ReplicaSet` can still re-use cached ones.

resource limits are satisfied by the input node's allocatable resources or not.
If yes, the node is assigned a score of 1, otherwise the node's score is not changed.
This admission plugin puts finalizer to every created PVC. The finalizer is
removed by PVCProtectionController when the PVC is not referenced by any
pods and thus the PVC can be deleted.

Add PodDisruptionBudget support in pod preemption
**What this PR does / why we need it**:
This PR adds the logic to make scheduler preemption aware of PodDisruptionBudget. Preemption tries to avoid preempting pods whose PDBs are violated by preemption. If preemption does not find any other pods to preempt, it will preempt pods despite violating their PDBs.
