Refact code using `set_fact`

At the moment, all the tasks using the file module are duplicated to have differents ownerships depending on the fact `is_ceph_infernalis`.
The goal of this commit is to have a new logic for this:
- First set facts depending on the `is_ceph_infernalis` fact
- Create the files or directories using the setted facts as ownerships.
