When operating as a forwarding DNS server, maas refuses queries from subnets it doesn't know about. A subnet must be added to MAAS in order for it to answer.

This is inconvenient because it requires adding subnets to MAAS which MAAS will never manage otherwise. For example, when using DNS-HA OpenStack deployed on MAAS, all of the subnets OpenStack clients might come from must be added to MAAS so that MAAS can be used as the DNS server for those clients, which must also resolve non MAAS owned domains, even though MAAS will never own machines on those subnets.
