Add metric collections for vSphere cloud provider operations

**What this PR does / why we need it**:
This PR adds metric collections for vSphere Cloud Provider Operations.

**Which issue this PR fixes** 
fixes #

**Special notes for your reviewer**:
Verified Prometheus pod is able to scrape vSphere metrics from Kubernetes Controller’s URL.

`providers/vsphere/vsphere.go` file is intentionally kept not formatted with gofmt, to keep diff review-able.

After review is complete, I will apply the formatting. 

**Release note**:

```release-note
None
```

@BaluDontu @tusharnt

@gnufied Verified with executing various operations on the Kubernetes Cluster deployed using this change.
