Open Stack

This probably applies to all deployment tools, so hopefully this reaches the
right folks.

In Havana, Cinder deprecated the use of specifying the module for configuring
backup drivers. Patch https://review.openstack.org/#/c/595372/ finally removed
the backwards compatibility handling for configs that still used the old way.

Looking through a quick search, it appears there may be some tools that are
still defaulting to setting the backup driver name using the patch. If your
project does not specify the full driver class path, please update these to do
so now.

Any questions, please reach out here or in the #openstack-cinder channel.

Thanks!
