Implement means for reflecting failed containers (i.e., those having exited non-zero) to better integrate `kube play` with systemd. The idea is to have the main PID of `kube play` exit non-zero in a configurable way such that systemd's restart policies can kick in. When using the default sdnotify-notify policy, the service container acts as the main PID to further reduce the resource footprint. In that case, before stopping the service container, Podman will lookup the exit codes of all non-infra containers. The service will then behave according to the following three exit-code policies: - `none`: exit 0 and ignore containers (default) - `any`: exit non-zero if _any_ container did - `all`: exit non-zero if _all_ containers did The upper values can be passed via a hidden `kube play --service-exit-code-propagation` flag which can be used by tests and later on by Quadlet. In case Podman acts as the main PID (i.e., when at least one container runs with an sdnotify-policy other than "ignore"), Podman will continue to wait for the service container to exit and reflect its exit code. Note that this commit also fixes a long-standing annoyance of the service container exiting non-zero. The underlying issue was that the service container had been stopped with SIGKILL instead of SIGTERM and hence exited non-zero. Fixing that was a prerequisite for the exit-code propagation to work but also improves the integration of `kube play` with systemd and hence Quadlet with systemd.
