Add support for rbd plugin to csi-translation-lib

Browse Source 
In support of csi-migration proposal here:
https://github.com/kubernetes/community/blob/master/contributors/design-proposals/storage/csi-migration.md

Will help with migration of in-tree RBD plugin ( kubernetes.io/rbd)
to RBD CSI driver ( rbd.csi.ceph.com ).

Fixes https://github.com/kubernetes/enhancements/issues/2923
