1. Proposed title of this feature request

[RFE] Support to prevent from using same pvc by multiple pods accidentally

3. What is the nature and description of the request?

- There are no way to restrict to be used pvc which is "in use" by other pods in same namespace(project)

4. Why does the customer need this? (List the business requirements here)
5. How would the customer like to achieve this? (List the functional requirements here)

Steps to Reproduce:
step-1. Create pvc

  $ oc get pvc
  NAME      LABELS    STATUS    VOLUME    CAPACITY   ACCESSMODES   AGE
  claim1    <none>    Bound     pv0001    1Gi        RWO           13s

step-2. Create pod(nfs-test) and use above pvc(claim1).

  $ oc describe pod nfs-test |grep -1 claim1
      Type:	PersistentVolumeClaim (a reference to a PersistentVolumeClaim in the same namespace)
      ClaimName:	claim1
      ReadOnly:	false

step-3. Create another pod(nfs-test2) and use same pvc(claim1).

  $ oc describe pod nfs-test2 |grep -1 claim1
      Type:	PersistentVolumeClaim (a reference to a PersistentVolumeClaim in the same namespace)
      ClaimName:	claim1
      ReadOnly:	false

- It is possible to use the pvc "in-use" by other pods.
- We want some options to prevent from using in-use pvc by other pods.


7. Is there already an existing RFE upstream or in Red Hat Bugzilla?

- No, as far as I searched.
