vSphere storage policy support for dynamic volume provisioning
Till now, vSphere cloud provider provides support to configure persistent volume with VSAN storage capabilities - kubernetes#42974. Right now this only works with VSAN.
Also there might be other use cases:
- The user might need a way to configure a policy on other datastores like VMFS, NFS etc.
- Use Storage IO control, VMCrypt policies for a persistent disk.
We can achieve about 2 use cases by using existing storage policies which are already created on vCenter using the Storage Policy Based Management service. The user will specify the SPBM policy ID as part of dynamic provisioning
- resultant persistent volume will have the policy configured with it.
- The persistent volume will be created on the compatible datastore that satisfies the storage policy requirements.
- If there are multiple compatible datastores, the datastore with the max free space would be chosen by default.
- If the user specifies the datastore along with the storage policy ID, the volume will created on this datastore if its compatible. In case if the user specified datastore is incompatible, it would error out the reasons for incompatibility to the user.
- Also, the user will be able to see the associations of persistent volume object with the policy on the vCenter once the volume is attached to the node.
For instance in the below example, the volume will created on a compatible datastore with max free space that satisfies the "Gold" storage policy requirements.
```
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: fast
provisioner: kubernetes.io/vsphere-volume
parameters:
diskformat: zeroedthick
storagepolicyName: Gold
```
For instance in the below example, the vSphere CP checks if "VSANDatastore" is compatible with "Gold" storage policy requirements. If yes, volume will be provisioned on "VSANDatastore" else it will error that "VSANDatastore" is not compatible with the exact reason for failure.
```
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: fast
provisioner: kubernetes.io/vsphere-volume
parameters:
diskformat: zeroedthick
storagepolicyName: Gold
datastore: VSANDatastore
```
As a part of this change, 4 commits have been added to this PR.
1. Vendor changes for vmware/govmomi
2. Changes to the VsphereVirtualDiskVolumeSource in the Kubernetes API. Added 2 additional fields StoragePolicyName, StoragePolicyID
3. Swagger and Open spec API changes.
4. vSphere Cloud Provider changes to implement the storage policy support.

Azure disk api
This is to update the AzureDiskApi and split it from the implementation which is caught in rebase hell...
Once this is merged, we'll get the implementation in.
@smarterclayton suggested this as a way to break the rebase hell logjam. request for a quick review.
Thanks!

Display <none> for "kubectl get pods -o wide" when node is empty.
**What this PR does / why we need it**:
If pods are pending due to no matched node to be scheduled, `Spec.NodeName` would be empty. In this case, "kubectl get pods -o wide" displays `<none>` instead of empty.

kubectl: Adding IPv6 brackets for IPv6 endpoints
This fixes the lack of IPv6 when printing the IP:Port tuple with kubectl
describe command.
Signed-off-by: André Martins <aanm90@gmail.com>
**What this PR does / why we need it**: This adds IPv6 brackets on IPv6 endpoints when using `kubectl describe service`
**Special notes for your reviewer**: Since the IP is a string I think the fastest way to detect if it's an IPv6 was to check for the presence of : in it. Let me know what you think.

Add Host field to TCPSocketAction
Currently, TCPSocketAction always uses Pod's IP in connection. But when a pod uses the host network, sometimes firewall rules may prevent kubelet from connecting through the Pod's IP.
This PR introduces the 'Host' field for TCPSocketAction, and if it is set to non-empty string, the probe will be performed on the configured host rather than the Pod's IP. This gives users an opportunity to explicitly specify 'localhost' as the target for the above situations.
```release-note
Add Host field to TCPSocketAction
