rbd: add generic ephemeral volume validation

Browse Source 
This commit adds the validation of csi RBD 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 is also included in this commit.
