Recent changes brought l2 vlan concept which do not have DHCP clients behind them and so DHCP relay is not required. Also, dhcpmon fails to launch on those vlans as their interfaces lack IP addresses. This PR limit launch of both DHCP relay and dhcpmon to L3 vlans only. singed-off-by: Tamer Ahmed <tamer.ahmed@microsoft.com>
