Call for testing: dhcpd role update

Hi all, As some of you know I largely rewrote the dhcpd role. Everyone who can set up or otherwise utilize a test network is highly encouraged to try it out. All feedback is greatly appreciated. The PR is here: https://github.com/debops/debops/pull/1471 Having users of the old dhcpd role review my changes is especially useful. Please consider taking a look! Thanks, Imre
