Fix Cluster-Autoscaler e2e on testgrid
Fix an e2e test failing in CI. The failures were caused by maximum nodes in test env being lower than the number of nodes required by the test.

Wait for clean old RSs statuses in the middle of Recreate rollouts
After https://github.com/kubernetes/kubernetes/pull/43508 got merged, we started returning ReplicaSets with no pods but with stale statuses back to the rollout functions. As a consequence, one of our e2e tests that checks if a Recreate Deployment runs pods from different versions, started flakying because the Deployment status may be incorrect. This change simply waits for the statuses to get cleaned up before proceeding with scaling up the new RS.

Make sure Teardown is called.
This will ensure that tests get a chance to clean up resources even if
setup failed part way through.

[Federation] Improve e2e test setup
This PR improves federation e2e test setup:
- reuses e2e framework setup (``NewDefaultFramework``) instead of duplicating it
- ensures ``FederationAfterEach`` is called if an error occurs in ``FederationBeforeEach`` (as per the [example](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/framework.go#L161) of the e2e framework)
- skips creation of a test namespace in the hosting cluster (not used for a federation e2e test)

Moved remaining util functions
moved cinder specific function back to volumes.go, will have to be extracted later when a cinder e2e package is created.
remove dupe code from common/volume.go
Moved [Volume] tags to KubeDescribe

Move autoscaling e2e tests to a separate directory
For fine-grain access control. Autoscaling team is expanding the e2e test coverage and the need for getting an approval for every PR is annoying.

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

Adding test to perform volume operations storm
**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.
This test will help validate issue reported at https://github.com/vmware/kubernetes/issues/71

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.
**Release note**:

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.
