Add "Terminating" status in kube_persistentvolumeclaim_status_phase metrics

[roystchiang]

What would you like to be added:

I would like to see which PVCs are in Terminating state in the kube_persistentvolumeclaim_status_phase metric

Why is this needed:

This will be useful to see how many PVCs are stuck or accidentally deleted. Right now, PVCs are either Bound, Lost, or Pending. If a PVC is in Terminating state because a pod is still using it, it will show up as Bound.

Describe the solution you'd like

Similar to #1013, we could expose the Terminating state
