Setting the volume_driver option explicitly even for iscsi backend is desirable, because if the user would switch from e.g. an nfs backend to iscsi, the volume_driver config option would not be changed during the Puppet run and still point to the nfs driver. Defaults to LVMISCSIDriver, can be overriden to LVMISERDriver. Change-Id: I860508ff92fce4add21c50e684e1717fc4f16622
