common: create ceph initial directories

Some users purge their environments and leave it in a non-optimal state.
e.g: packages are still installed but /etc/ceph and /var/lib/ceph don't
exist anymore. This will result in multiple failures across the play,
sometimes hard to detect. Populating these directories "just in case"
should help us solving these problems.

Closes: #1253
