Disable autoscaling before removing autoscaled node pool
This is to prevent flakes due to API calls failing in AfterEach during master restart, which is triggered by deleting an autoscaled node pool. Adding disable call before deleting node pool should prevent this as we'll wait for master restart in disableAutoscaler function.
While it may be faster to wait after deletion of autoscaled node pools, this is less complex and will be easier to remove in the future when changing autoscaling setttings no longer triggers master restart.

Change RBAC storage version to v1 for 1.9
v1 was introduced in 1.8, but storage version remained at v1beta1 to accommodate HA rolling upgrades. in 1.9, we can change the persisted and preferred version to v1
```release-note
RBAC objects are now stored in etcd in v1 format. After completing an upgrade to 1.9, RBAC objects (Roles, RoleBindings, ClusterRoles, ClusterRoleBindings) should be migrated to ensure all persisted objects are written in `v1` format, prior to `v1alpha1` support being removed in a future release.

Remake cluster size autoscaling scale to zero test
This PR affects only cluster size autoscaling test suite. Changes:
* check whether autoscaling for is enabled by looking for a node group with a given max number of nodes instead of min as the field is omitted if value is 0
* split scale to zero test into GKE & GCE versions, add GKE-specific setup and verification

Prepull images after disk eviction tests
Example failure: https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-node-kubelet-flaky/2855
Disk eviction tests trigger image garbage collection. It can remove images required for subsequent tests.
This results in the error during pod creation:
`timed out waiting for the condition`
You can see in the events after the test:

Fix sed command to not try shell redirection
RunCmd uses Go's os/exec library to run commands directly. Since these
are not run through a shell, we can't use shell syntax for piping or
file redirection. The proper way to do that is to create a Command
object and set the Std{in,out,err} pipes appropriately. Luckily sed
can handle the behavior we need without having to manually set this up.

Improve PVC ref volume metric test robustness
This test has been flaking. The current working theory is that
volume stats collection didn't run in time to grab the metrics
from the newly created pod.
Made the following changes:
- Added more logs to help debug future failures
- Poll metrics a few additional times before failing the test

Added device plugin e2e kubelet failure test
Signed-off-by: Renaud Gaubert <renaud.gaubert@gmail.com>
**What this PR does / why we need it**:
This is part of issue #52859 (fixes#52859)
This PR adds a e2e_node test for the device plugin.
Specifically it implements testing of failure handling by the device plugin components in case Kubelet restart / crashes.
I might try to refactor the GPU tests in a later PR.

Fixed intermitant e2e aggregator test on GKE.
**What this PR does / why we need it**: Issue was caused by another test cleaning up its namespace.
This caused the namespace controller to try to clean up that namespace.
This involves deleting all flunders under that namespace.
However the sample-apiserver was not honoring the namespace filter.
So the flunders for the test would randomly disappear.
