Subject: [PATCH] Add fenced systemd and example configs

This should be good enough to get single node mounts up and running with
fenced with minimal effort.  The example config will need to be copied
to /etc/scoutfs/scoutfs-fenced.conf for it to be functional, so this
still requires specific opt-in and wont accidentally run for multi-node
systems.
