Kevin Carter a372183af9 Add lxc.haltsignal to container configs 
This change adds the lxc.haltsignal option to the container config which
ensures containers are gracefully stopped but quickly.

Presently, when a container is restart they can hang for 20 - 30 seconds
which is due to the fact that the default stop signal is SIGPWR.
While the hang when stopping a container is not 100% reproducible in all
environments it can be seen when simply executing `lxc-stop`. If the
user were to stream the container journal while stopping the container
it's would be seen that the container hangs when trying to shutdown some
systemd services. If the `lxc-stop` command is executed a second time the
container is stopped more forcibly with SIGRTMIN+3. This change is using
an example stop signal from the lxc documentation [0] which is
implementing a Real-time signal, SIGRTMIN+n. More on the signal used can
be found here [1].
