Use the same pattern everywhere in the e2e test
harness, use busybox (from dockerhub) instead
of using the one from k8s.gcr.io registry.

Use apps/v1 Deployment/ReplicaSet in controller and kubectl
This updates the Deployment controller and integration/e2e tests to use apps/v1, as part of #55714.
This also requires updating any other components that use the `deployment/util` package, most notably `kubectl`. That means client versions 1.11 and above will only work with server versions 1.9 and above. This is well within our client-server version skew policy of +/-1 minor version.
However, this PR *only* updates the parts of `kubectl` that used `deployment/util`. So although kubectl now requires apps/v1, it still also depends on extensions/v1beta1. Migrating other parts of kubectl to apps/v1 is beyond the scope of this PR, which was just to change the Deployment controller and fix all the fallout.
```release-note
kubectl: This client version requires the `apps/v1` APIs, so it will not work against a cluster version older than v1.9.0. Note that kubectl only guarantees compatibility with clusters that are +/-1 minor version away.

Remove the use of storage class beta annotations in e2e tests.
**What this PR does / why we need it**:
Since we are going to remove storage class beta annotations, we'd like to remove the use of it in e2e tests to avoid upgrade test issues when it's finally removed.

[e2e gce-ingress] Scale test to measure ingress create/update latency
**What this PR does / why we need it**:
Adding a basic scale test. Test procedure:
- Create O(1) ingresses, measure creation latency for each ingress.
- Create and update one more ingress, do similar measurement on create & update latency.
- Repeat first two steps with O(10) ingresses.
- Repeat first two steps with O(100) ingresses.
Couple side notes:
- Each ingress reference a separate service.
- All services share the same set of backend pods.
- All ingress share one TLS secret.

Promote Statefulset controller and its e2e tests to use apps/v1
**What this PR does / why we need it**:
Promotes the statefulset controller to use to use the latest apps group [apps/v1](https://github.com/kubernetes/kubernetes/pull/53679)

Fixes # https://github.com/kubernetes/kubernetes/issues/55714
**Special notes for your reviewer**:
* Listerexpansion for v1 `k8s.io/client-go/listers/apps/v1` (was recently done for v1beta2)
* `v1beta2` && `v1` had `ObservedGeneration` as `int64` where as `v1beta1` and rest of the code (including conversion) is expecting `ObservedGeneration` to be `*int64`
```
type StatefulSetStatus struct {
// observedGeneration is the most recent generation observed for this StatefulSet. It corresponds to the
// StatefulSet's generation, which is updated on mutation by the API Server.
// +optional
ObservedGeneration int64 `json:"observedGeneration,omitempty" protobuf:"varint,1,opt,name=observedGeneration"`
```
* for kubectl's `rollback` and `history` commands a couple functions have been duplicated to allow us to use `v1` version instead of `v1beta1` for statefulsets, while the older functions are still used by other controllers.
We should be able to remove these duplicates once all the controllers are moved.
If this aligns with the plan then i could move other controllers too.

E2E scale test for vSphere Cloud Provider Volume lifecycle operations
This PR adds an E2E test for vSphere Cloud Provider which will create/attach/detach/detach the volumes at scale with multiple threads based on user configurable values for number of volumes, volumes per pod and number of threads. (Since this is a scale test, number of threads would be low. This is only used to speed up the operation)
Test performs following tasks.
1. Create Storage Classes of 4 Categories (Default, SC with Non Default Datastore, SC with SPBM Policy, SC with VSAN Storage Capalibilies.)
2. Read VCP_SCALE_VOLUME_COUNT from System Environment.
3. Launch VCP_SCALE_INSTANCES go routines for creating VCP_SCALE_VOLUME_COUNT volumes. Each go routine is responsible for create/attach of VCP_SCALE_VOLUME_COUNT/VCP_SCALE_INSTANCES volumes.
4. Read VCP_SCALE_VOLUMES_PER_POD from System Environment. Each pod will be have VCP_SCALE_VOLUMES_PER_POD attached to it.
5. Once all the go routines are completed, we delete all the pods and volumes.
