Remove conformance tag for internet connectivity
**What this PR does / why we need it**:
ICMP ping is not available in many environments, so we should avoid
using a e2e test based the premise as a conformance test.

**Special notes for your reviewer**:
Part of Fix for #52098, Please see #51287 for more discussion

The e2e iPerf test case currently only runs in IPv4 mode.
This change add an option to run an iPerf test in IPv6 mode (i.e. by running
iPerf with a "-V" command line flag), so that the test can be run on
IPv6-only clusters.

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
fixes#53150
