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.
