When running the switch2container playbook on a Debian based system
then the systemd unit path isn't the same than Red Hat based system.
Because the systemd unit files aren't removed then the new container
systemd unit isn't take in count.

The task "remove old systemd unit file" under "switching from
non-containerized to containerized ceph rgw" only removes
the ceph-radosgw@.service file. The task should also remove
the ceph-radosgw.target file, like the "remove old systemd unit
files" tasks for the mons, mgrs, osds, etc, in order to clean up
all of the unused systemd unit files.

When rgw and osd are collocated, the current workflow prevents from
scaling out the radosgw_num_instances parameter when rerunning the
playbook.
The environment file used in the rgw systemd template is rendered when
executing the `ceph-rgw` role but during a new run of the playbook (in
order to scale out rgw instances), handlers are triggered from `ceph-osd`
role which is run before `ceph-rgw`, therefore it tries to start the new
rgw daemon whereas its corresponding environment file hasn't been
rendered yet and fails like following:
```
ceph-radosgw@rgw.ceph4osd3.rgw1.service failed to run 'start-pre' task: No such file or directory
```
This commit moves the tasks generating this file in `ceph-config` role
so it is generated early.

When a container is already running on a non containerized node then the
umount ceph partition task is skipped.
This is due to the container ps command which always returns 0 even if
the filter matches nothing.
We should run the umount task when:
1/ the container command is failing (not installed) : rc != 0
2/ the container command reports running ceph-osd containers : rc == 0
Also we should not fail on the ceph directory listing.

When switching from a baremetal deployment to a containerized deployment
we only umount the OSD data partition.
If the OSD is encrypted (dmcrypt: true) then there's an additional
partition (part number 5) used for the lockbox and mount in the
/var/lib/ceph/osd-lockbox/ directory.
Because this partition isn't umount then the containerized OSD aren't
able to start. The partition is still mount by the system and can't be
remount from the container.

By changing the set ownership command from using the file module in combination with a with_items loop to a raw chown command, we can achieve a 98% performance increase here.
On a ceph cluster with a significant amount of directories and files in /var/lib/ceph, the file module has to run checks on ownership of all those directories and files to determine whether a change is needed.
In this case, we just want to explicitly set the ownership of all these directories and files to the ceph_uid
Added context note to all set proper ownership tasks

This commit splits the current `ceph-container-common` role.
This introduces a new role `ceph-container-engine` which handles the
tasks specific to the installation of containers tools (docker/podman).
This is needed for the ceph-dashboard implementation for 2 main reasons:
1/ Since the ceph-dashboard stack is only containerized, we must install
everything needed to run containers even in non containerized
deployments. Splitting this role allows us to not have to call the full
`ceph-container-common` role which would run a bunch of unneeded tasks
that would have been skipped anyway.
2/ The current implementation would have required to run
`ceph-container-common` on all ceph-clients nodes which would have been
conflicting with 9d3517c670 (we don't want
to run ceph-container-common on all client nodes, see mentioned commit
for more details)

`ceph-mon` tries to redeploy monitors because it assumes it was not yet

sometimes we play the whole role `ceph-defaults` just to access the
