When upgrading the host operating system we'll also replace docker
with podman; ceph-ansible provides for a special playbook meant
to refresh the systemd units to work with podman.
This change adds a task which on upgrade will execute the special
playbook. It requires ceph_ansible_limit to be set by the user as
that gets translated into a --limit option for the playbook execution
so that it runs only against a specific node undergoing upgrade
of the host operating system.
