- Add support for AppArmor
 - Gracefully stop containers and pods on shutdown

I found out that If you change location of containers to persistent storage instead of tmpfs, starting them will fail unless they have been stopped. If this is the case that reboot has occurred before pods and containers have been stopped, they cannot be started, they have to be removed and re-created. Change in initscript tries to avoid that. Even if containers are running at tmpfs, this won't hurt. Still, if something happens and system hangs/reboots/etc, script won't save you from that. It's just a attempt to make things better.
I also enabled AppArmor support for future possibilities.

Ship podman with defaults more coherent with user expectations and
more likely to work out-of-the-box.
