Yati Padia cfb6abc067 e2e: update snapshot restore e2e to check data consistency
Currently, in rbd snapshot restore and volume clone E2E we
are not checking any data consistency after doing snapshot
restore or volume clone. Hence, this PR writes the data in
the PVC and checks the checksum of the file and verify it with
the snapshot or cloned PVC.
