Make sure DNS Gossip converges correctly.
...
- Abide by gossip interface (return nil, not empty gossip) so gossip converges!
- Make sure we don't say an old entry version is new to us; add some more tests.
- Add dns test for 3 (or N) hosts
- Extend mock gossip router to ensure reconsumption off diffs yield nil
- Don't increment version when re-adding existing entry.

Gossip-based DNS embedded in the router.
...
- Nameserver holds a sorted list of (hostname, peer, container id, ip) tuples.
- Entries are gossiped using topology gossip / broadcast - only new/updated entries
are propogated as expected.
- Entries for a given peer are removed when the connection to the peer is lost.
- Entries are tombstoned when containers die. Tombstones are kept for 10mins,
as they do not need to survive partition, only gossip propagation delay.

Split part of DNSServer.Start() to a separate ActivateAndServe()
...
Specifically, move the part that blocks, and call that as necessary.
This means Start() can run on the caller's goroutine and avoid race conditions.

The shuffleAnswers() call ends up acting on the same data,
so it seems simplest to resolve ownership arguments by copying.
