Add etcd middleware This middleware acts in the same way as SkyDNS. We might add options to allow it to be behave different, but for now it will suffice. A Corefile like: .:1053 { etcd miek.nl proxy . 8.8.8.8:53 } will perform lookup in etcd and proxy everything not miek.nl to Google for further resolution. The internal etcd forwarding *also* uses the proxy infrastructure, meaning you get health check and such for (almost) free

Add Stub resolving SkyDNS can forward requests from one instance to another. Add this base infrastructure for this feature to CoreDNS. Add more tests as well.
