Wrap stopping podman -t with systemd timeouts
Currently with KillMode=none, if podman -t hangs, the command repeats
leaving the process and its cgroup around.
But if a stop/start command hangs, we should not start another one.
Instead time it out properly via TimeoutStopSec set to the 2x of
the timeout given to the managed podman action. Then if it expires,
kill its cgroup all the way (KillMode=control-group is a default)
before rerunning the same operation. Also note that using KilMode
process is not recommended by systemd man pages.
Increase the grace stop timeout defaults 10->42s to align it with:
