Dmitry Tantsur 39eb964134 Disable DHCP completely when no nodes are on introspection ... Currently we keep DHCP always open for new nodes. This is an overkill, as we always know which nodes are on introspection. It also causes problems when not all node NIC's are registered in Ironic, as these NIC's might get DHCP from our server. This change reduces probability of wrong nodes accessing our DHCP by REJECT'ing all DHCP requests when no nodes are on introspection and node_not_found_hook is not set. It does not solve the problem completely: conflicts are still possible during the introspection.
