Add e2e test for a volume + its clone used on the same node
CSI driver need to pass special mount opts to XFS filesystem to be able to mount a volume + its clone or its restored snapshot on the same node. Add a test to exhibit this behavior. The test is optional for now, giving CSI drivers time to fix it.
