Brian Haley ea85e39660 Force arp_responder to True when DVR and tunneling enabled
After [1] and [2], the ARP responder needs to be enabled
if DVR and tunneling are enabled or ARP will not work. If
it is False we will log a message and force it to True.

When the ``enable_distributed_routing`` (DVR) configuration option is set
to ``True`` and tunneling is enabled, the ``arp_responder`` option will
be forced to ``True`` since it is now required in order for ARP to work
properly. For more information, see bug
