As of nautilus, the initial keyrings list has changed, it means when
upgrading from Luminous or Mimic, it is expected there's a mismatch
between what is found on the cluster and the expected initial keyring
list hardcoded in ceph_key module. We shouldn't fail when upgrading to
nautilus.

Currently the default crush rule value is added to the ceph config
on the mon nodes as an extra configuration applied after the template
generation via the ansible ini module.
This implies two behaviors:
1/ On each ceph-ansible run, the ceph.conf will be regenerated via
ceph-config+template and then ceph-mon+ini_file. This leads to a
non necessary daemons restart.
2/ When other ceph daemons are collocated on the monitor nodes
(like mgr or rgw), the default crush rule value will be erased by
the ceph.conf template (mon -> mgr -> rgw).
This patch adds the osd_pool_default_crush_rule config to the ceph
template and only for the monitor nodes (like crush_rules.yml).
The default crush rule id is read (if exist) from the current ceph
configuration.
The default configuration is -1 (ceph default).

instead of using `RuntimeDirectory` parameter in systemd unit files,
let's use a systemd `tmpfiles.d` to ensure `/run/ceph`.
Explanation:
`podman` doesn't create the `/var/run/ceph` if it doesn't exist the time
where the container is run while `docker` used to create it.
In case of `switch_to_containers` scenario, `/run/ceph` gets created by
a tmpfiles.d systemd file; when switching to containers, the systemd
unit file complains because `/run/ceph` already exists
The better fix would be to ensure `/usr/lib/tmpfiles.d/ceph-common.conf`
is removed and only rely on `RuntimeDirectory` from systemd unit file parameter
but we come from a non-containerized environment which is already running,
it means `/run/ceph` is already created and when starting the unit to
start the container, systemd will still complain and we can't simply
remove the directory if daemons are collocated.

On containerized deployment, if a mon is stopped, the socket is not

purge playbook has been run.
Typical error:
```
fatal: [osd0]: FAILED! => {}
MSG:

```
the fact is not set because of this previous failure earlier:
```

"cmd": "docker exec ceph-mon-mon0 ceph --cluster test daemon mon.mon0 config get osd_pool_default_pg_num",

Running the last portion (insert new default and add new default crush

wrong since ceph CLI calls usually end up on the master having the

So if we run the command and end up on another mon the creation will
