By default, when shutting NM down, systemd will kill everything in its cgroup. But this can cause problems (eg, NM thinking that dhclient crashed and then taking down an interface that it would otherwise have left up). Fix this by setting KillMode=process, which tells systemd to only kill NM itself, and let NM kill its children. https://bugzilla.redhat.com/show_bug.cgi?id=876218
