Currently we're only able to use podman on ubuntu if podman's
installation is done manually before the ceph-ansible execution
because the deb package is present in an external repository.
We already manage the docker-ce installation via an external
repository so we should be able to allow the podman installation
with the same mechanism too.

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)
