This allows the tasks that depend on the variables set by those tasks to

When deploying the ceph OSD via the packages then the ceph-osd@.service
unit is configured as enabled-runtime.
This means that each ceph-osd service will inherit from that state.
The enabled-runtime systemd state doesn't survive after a reboot.
For non containerized deployment the OSD are still starting after a
reboot because there's the ceph-volume@.service and/or ceph-osd.target
units that are doing the job.
$ systemctl list-unit-files|egrep '^ceph-(volume|osd)'|column -t
ceph-osd@.service enabled-runtime
ceph-volume@.service enabled
ceph-osd.target enabled
When switching to containerized deployment we are stopping/disabling
ceph-osd@XX.servive, ceph-volume and ceph.target and then removing the
systemd unit files.
But the new systemd units for containerized ceph-osd service will still
inherit from ceph-osd@.service unit file.
As a consequence, if an OSD host is rebooting after the playbook execution
then the ceph-osd service won't come back because they aren't enabled at
boot.
This patch also adds a reboot and testinfra run after running the switch
to container playbook.

The ceph status command returns a lot of information stored in variables

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 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

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.

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)
