podman rm/stop --cidfile

Add a --cidfile flag to podman rm/stop to pass a container ID via a
file.  Podman run already provides the functionaly to store the ID
in a specified file which we now complete with rm/stop.  This allows
for a better life-cycle management in systemd services.  Note that
--cdifile can be specified multiple times to rm/stop.
