Add --in-pod parameter for systemd commands

[ttsak]

systemd scripts depend an a pod to exist but this is not created unless the in-pod parameter is added

Hi,

really nice work the podman-composer. IMHO it shouldn't be
ExecStartPre=-{script} --in-pod %i up --no-start
but
ExecStartPre=-{script} --in-pod pod_%i up --no-start
in the unit file.

Also it might be good to have a "ExecStopPost" line to remove the pod:
ExecStopPost=/usr/bin/podman pod rm pod_%i

Thank you for your great work,
Ralf

--in-pod is now default, so this PR is no longer needed. Thanks a lot for caring about this feature.
