Use storage.k8s.io/v1 in tests instead of v1beta1
This is trimmed version of #42477 and contains only tests of the new storage API. Together with #43285 it passes all dynamic provisioning tests on my GCE.
I did not change vsphere_utils.go and vsphere_volume_diskformat.go as @divyenpatel runs master vsphere tests with Kubernetes 1.5 - @divyenpatel, did I get it right?

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.
In particular, we should not assume ControllerRefs are necessarily set.
However, we can still use ControllerRefs that do exist to avoid
interfering with controllers that do use it.

Add guards for StatefulSet and AppArmor upgrade testing
This PR adds automated upgrade infrastructure to allow test suites to know what versions and node images are going to be testing and whether or not they should be skipped. It also adds a guard to prevent StatefulSets from being tested with versions prior to 1.5.0, and a guard to prevent AppArmor from running on distros other than gci and ubuntu.

Wait for garbagecollector to be synced in test
Fix#42952
Without the `cache.WaitForCacheSync` in the test, it's possible for the GC to get a merged event of RC's creation and its update (update to deletionTimestamp != 0), before GC gets the creation event of the pod, so it's possible the GC will handle the foreground deletion of the RC before it adds the Pod to the dependency graph, thus the race.
With the `cache.WaitForCacheSync` in the test, because GC runs a single thread to process graph changes, it's guaranteed the Pod will be added to the dependency graph before GC handles the foreground deletion of the RC.
Note that this pull fixes the race in the test. The race described in the first point of #26120 still exists.
