In order to revert to a snapshot in the LVM driver (and very likely other drivers) the list of access rules is needed, so this change modifies the driver interface to provide this extra information. This change requires preventing a revert to snapshot operation while access rules on the affected share are out of sync. Closes bug: 1658133 Change-Id: Ia6678bb0e484f9c8f8b05d90e514801ae9baa94b
