[Kea-users] Updating kea.conf - does it need a daemon restart

Gotta love systemd :(

I abandoned the packaged systemd service definitions and approach for a 
more "sane" approach of starting keactrl and letting it manage the 
various parts of kea, rather than having one service for each component.

I also install kea directly (to /opt, to keep things cleaner) as 
Debian/Ubuntu is only on isc-kea-1.1.0-1
