Perform resize of mounted volume if necessary
Under certain conditions - we must perform resize of volume even when it is mounted. This enables us to get around problem of resizing volumes used by deployments etc.
```release-note
Allow expanding mounted volumes

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)
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
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.

The local-volume bootstrapper/provisioner configuration format changed in
https://github.com/kubernetes-incubator/external-storage/pull/352
This format is exposed in v2.0.0 of the provisioner and boostratpper images.
This PR updates the e2e test config, so that the existing tests continue
to work.
This e2e test tests the CSI volume plugin in kubernetes with
a CSI hostPath driver. It is also setup to be able to be
tested with more drivers in the future.

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.

Adding e2e test to verify volume attach status after master kubelet restart
**What this PR does / why we need it**:
This PR adds test to verify volume remains attached after the kubelet is restarted on master node.
**Which issue this PR fixes** :
fixes vmware#274
**Special notes for your reviewer**:
This test does not run as part of existing sig-storage test grid. It has been tested internally at VMware.

VSphere cloud provider code refactoring
The current PR tracks the vSphere Cloud Provider code refactoring which includes the following changes.
- VCLib Package - A framework used by vSphere cloud provider for managing the vSphere entities. VCLib package mainly does the following:
- Volume management on datastore (Create/Delete)
- Volume management on Virtual Machines (Attach/Detach)
- Storage Policy Management
- vSphere Cloud Provider changes to implement the cloud provider interfaces by calling into VCLib package.
- Modifications to e2e tests to accomodate the latest design changes.

improve error handling in e2e helpers
**What this PR does / why we need it**:
Changes most of the volume related helper funcs to return error rather than calling `Expect`. This is a better programming practice, is consistent with Go and Kubernetes, and allows helper funcs that create multiple resources to perform cleanup.
