This adds ceph-*.target systemd unit files support for containerized
deployments.
This also fixes a regression introduced by PR #6719 (rgw and nfs systemd
units not getting purged)

This commit isolates the systemd unit files generation for containers into
separate yml files in order to be able importing each corresponding roles
without playing all tasks.
This is needed so we can run ceph-ansible to render systemd unit files
so they call podman instead of docker.
