ceph-ansible has undergone significant refactoring in their v3
development, adding new required roles such as ceph-defaults and
ceph-config, which are used to provide vars and configuration to
the ceph service roles. These roles must be executed before the
service roles to avoid missing vars[1][2].
During the v3 refactoring, ceph-common was removed as a galaxy-style
role dependency in the service roles meta files[3]. This means we
will need to explicitly execute ceph-common from now on also.
This change adds the defaults and config roles and executes them.
Also some minor cleanup such as alphabetizing the OpenStack roles
list is done.
Also added is an upgrade playbook, reno, and docs to assist in
cleaning up the older galaxy-named ceph common roles which are
no longer galaxy namespaced in our cloning configuration.
