test/e2e_node: prepull images with CRI
Part of https://github.com/kubernetes/kubernetes/issues/40739
- This PR builds on top of #40525 (and contains one commit from #40525)
- The second commit contains a tiny change in the `Makefile`.
- Third commit is a patch to be able to prepull images using the CRI (as opposed to run `docker` to pull images which doesn't make sense if you're using CRI most of the times)
Marked WIP till #40525 makes its way into master

tests: e2e-node: refactor node-problem-detector test to avoid selinux…
Fixes https://github.com/kubernetes/kubernetes/issues/43401
This test creates a file in /tmp on the host and creates a HostPath volume in the container to so that the host can inject messages into the logfile being read by the node problem detector in the container. However, selinux prohibits the container from reading files out of /tmp on the host.
This PR modifies the test to create the log file in an EmptyDir volume instead, which will be properly labeled for container access.

**What this PR does / why we need it**:
Adding new test to perform volume operations storm
Test Steps
1. Create storage class for thin Provisioning.
2. Create 30 PVCs using above storage class in annotation, requesting 2 GB files.
3. Wait until all disks are ready and all PVs and PVCs get bind. (**CreateVolume** storm)
4. Create pod to mount volumes using PVCs created in step 2. (**AttachDisk** storm)
5. Wait for pod status to be running.
6. Verify all volumes accessible and available in the pod.
7. Delete pod.
8. wait until volumes gets detached. (**DetachDisk** storm)
9. Delete all PVCs. This should delete all Disks. (**DeleteVolume** storm)
10. Delete storage class.

Apply [Feature:Volumes] to subset of tests in volumes.go
**What this PR does / why we need it**:
According to [this test doc](https://github.com/kubernetes/community/blob/master/contributors/devel/e2e-tests.md#kinds-of-tests), the `[Feature:xyz]` tag indicates that the tests have a non-default requirements and should not be run in the core suite. Previously all test in _e2e/volumes.go_ were tagged `[Feature:Volumes]` but I believe only six of the tests warrant this tag: iSCSI, GlusterFS, Ceph-RBD, Ceph-FS, vSPhere, and Cinder. The remaining tests (NFS, PD, ConfigMap) do not need the `Feature:` tag.
**Special notes for your reviewer**:
I moved the `[Volume]` tags from the `It`'s to the outer `KubeDescribe` to simplify the `It` text and remove redundancy.

De-Flake PersistentVolume E2E: Isolate resources with selectors
PersistentVolume tests continue to flake because tests Claims often bind to other, parallel tests' volumes. This is addressed by isolating test resource with selector labels specific to each test namespace. Doing so enables deterministic binding within each test space and allows tests to run in parallel.
1. Assign selector label to volumes and claims per test.
2. Remove `[Serial]` tag

replicaset adopt and release e2e tests
**What this PR does / why we need it**: adds e2e tests for replicaset pod adoption and release
**Which issue this PR fixes** fixes#39962
**Special notes for your reviewer**: for adoption pod is created, a replicaset with a selector matching the pod's label is created and then we check for the pod being in the list of pods of the replicaset. For release, a replicaset with two replicas is created, the label of one of them is patched and then we check that that pod is no longer in the list of pods of the replicaset.
For checking the list of pods the `framework.PodsCreated` is used, maybe the name is not very adecuate given that it is used to return the pods belonging to one replicaset, no matter how they were created. Also, the patching is done through `framework.KubectlOrDie`, not sure if this is better that calling the API directly.

Fix problems of not-starting image pullers
In e2e.go there are the following lines:
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/e2e.go#L150
```
if err := framework.WaitForPodsSuccess(c, metav1.NamespaceSystem, framework.ImagePullerLabels, imagePrePullingTimeout); err != nil {
// There is no guarantee that the image pulling will succeed in 3 minutes
// and we don't even run the image puller on all platforms (including GKE).
// We wait for it so we get an indication of failures in the logs, and to
// maximize benefit of image pre-pulling.
framework.Logf("WARNING: Image pulling pods failed to enter success in %v: %v", imagePrePullingTimeout, err)
}
```
However, few lines above:
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/e2e.go#L143
we were waiting for all image pullers to actually enter Success state. It's pretty clear that the latter wasn't expected.

**What this PR does / why we need it**:
Adding new tests to e2e/vsphere_volume_placement.go
Below is the tests description and test steps.
**Test Back-to-back pod creation/deletion with different volume sources on the same worker node**
1. Create volumes - vmdk2, vmdk1 is created in the test setup.
2. Create pod Spec - pod-SpecA with volume path of vmdk1 and NodeSelector set to label assigned to node1.
3. Create pod Spec - pod-SpecB with volume path of vmdk2 and NodeSelector set to label assigned to node1.
4. Create pod-A using pod-SpecA and wait for pod to become ready.
5. Create pod-B using pod-SpecB and wait for POD to become ready.
6. Verify volumes are attached to the node.
7. Create empty file on the volume to make sure volume is accessible. (Perform this step on pod-A and pod-B)
8. Verify file created in step 5 is present on the volume. (perform this step on pod-A and pod-B)
9. Delete pod-A and pod-B
10. Repeatedly (5 times) perform step 4 to 9 and verify associated volume's content is matching.
11. Wait for vmdk1 and vmdk2 to be detached from node.
12. Delete vmdk1 and vmdk2
**Test multiple volumes from different datastore within the same pod**
1. Create volumes - vmdk2 on non default shared datastore.
2. Create pod Spec with volume path of vmdk1 (vmdk1 is created in test setup on default datastore) and vmdk2.
3. Create pod using spec created in step-2 and wait for pod to become ready.
4. Verify both volumes are attached to the node on which pod are created. Write some data to make sure volume are accessible.
5. Delete pod.
6. Wait for vmdk1 and vmdk2 to be detached from node.
7. Create pod using spec created in step-2 and wait for pod to become ready.

for the last issue, we look at `/sys/fs/cgroup/memory.stat[rss]` value which if you have global accounting enabled on systemd machines (as expected) will report 0 because nothing runs local to the root cgroup. we really want to be showing the total_rss value for non-leaf cgroups so we get the full hierarchy of usage.

kubectl: Use v1.5-compatible ownership logic when listing dependents.
**What this PR does / why we need it**:
This restores compatibility between kubectl 1.6 and clusters running Kubernetes 1.5.x. It introduces transitional ownership logic in which the client considers ControllerRef when it exists, but does not require it to exist.
If we were to ignore ControllerRef altogether (pre-1.6 client behavior), we would introduce a new failure mode in v1.6 because controllers that used to get stuck due to selector overlap will now make progress. For example, that means when reaping ReplicaSets of an overlapping Deployment, we would risk deleting ReplicaSets belonging to a different Deployment that we aren't about to delete.
This transitional logic avoids such surprises in 1.6 clusters, and does no worse than kubectl 1.5 did in 1.5 clusters. To prevent this when kubectl 1.5 is used against 1.6 clusters, we can cherrypick this change.

The test blindly checked all "pause" processes on the node, assuming
they were all infra containers. This change takes a snapshot of all
existing "pause" processes on the node, and exclude them in the
validation. The test still relies on the fact that it runs exclusively
on the node. If that assumption changes, we will need other methods to
locate the PIDs of the infra containers.
