The replication v1 implementation in Cinder was deprecated in the Mitaka release in favor of the v2 "Cheesecake" version. Support was kept in the client for backwards compatibility, but it has now been several releases and these options should be removed. Closes-bug: #1705470 Change-Id: I978a39a552fffc9ac7ba6e4726d1df2072fa45ba Signed-off-by: Sean McGinnis <sean.mcginnis@gmail.com>
