Notes on gossip support

• We use weave mesh's gossip functionality, which supports gossip of a CRDT
• protokube listens on 0.0.0.0:3999
• dns-controller listens on 0.0.0.0:3998
• The seed for dns-controller is protokube, discovered on 127.0.0.1:3999
• The real seeding is done by protokube, which currently finds peers by querying the cloud provider

DNS

• We implement a dnsprovider backed by our local gossip state
• We write to /etc/hosts; this is sort of hacky but avoids the need for a custom local resolver
