Uses a slightly modified version of https://github.com/kubernetes-incubator/external-storage/blob/master/ceph/cephfs/cephfs_provisioner/cephfs_provisioner.py This should be rewritten properly in Go, but for it works for now - for demonstration purposes TODO: * readOnly is not taken into account * controllerServer.DeleteVolume does nothing
