cephfs: add validation for generic ephemeral volumes

Browse Source 
This commit adds the validation of csi cephfs driver to work with
ephemeral volume support. With ephemeral volume support a user can
specify ephemeral volumes in its pod spec and tie the lifecycle
of the PVC with the POD.

An example POD spec also included in this commit.
