Ivan Kolodyazhny 447f141d4f Added support for fake drivers as Cinder backend
FakeLoggingVolumeDriver  will be used for functional Cinder tests to
prevent dependencies on any storage.

FakeGateDriver is based on LVM and will be used to run Tempest tests for
such features like CG's, replication, etc.
