CSIMigrationvSphere feature gate is enabled, user should not upgrade to Kubernetes v1.22. vSphere CSI Driver does not support Kubernetes v1.22 yet because it uses v1beta1 CRD APIs. Support for v1.22 will be added at a later release. Check the following document for supported Kubernetes releases for a given [vSphere CSI Driver version](https://vsphere-csi-driver.sigs.k8s.io/compatiblity_matrix.html#compatibility-matrix-for-vsphere-csi-driver).

### Workloads that saturate nodes with pods may see pods...

In-tree cloud provider bug fixes and improvements included:
- Adding initial Zones support to the provider using vSphere Tags
- Improving the testing harness for the cloud provider by introducing vcsim for automated testing

- Unlocked the `CSIMigrationvSphere` feature gate.
  The change allow users to continue using the in-tree vSphere driver,pending a vSphere

### Other (Cleanup or Flake)

- Fixes an issue where the vsphere cloud provider will not trust a certificate if:
  - The issuer of the certificate is unknown (x509.UnknownAuthorityError)
  - The requested name does not match the set of authorized names (x509.HostnameError)

- Adds support for vSphere volumes on Windows ([#80911](https://github.com/kubernetes/kubernetes/pull/80911), [@gab-satchi](https://github.com/gab-satchi))

## API Changes
