SkyDNS - DNS service discovery for etcd

SkyDNS is a distributed service for announcement and discovery of services built on top of etcd. It utilizes DNS queries to discover available services. This is done by leveraging SRV records in DNS, with special meaning given to subdomains, priorities and weights.

• Does away with Raft and uses etcd (which uses raft).
• Makes it possible to query arbitrary domain names.
• Is a thin layer above etcd, that translates etcd keys and values to the DNS.
• Does DNSSEC with NSEC3 instead of NSEC.
