DNS lookups should not be case sensitive.
...
- On-the-wire gossip messages are sorted case sensitive, but in memory they are sorted case-insensitive.
- Add test for case insensitive match on multiple names.

This means it also works when the docker daemon restarts a container.

Test for recursive DNS queries & compression.
...
Note this doesn't test the golang resolver, where the original error
was found, as I can't find a way to point the golang resolver at a
custom dns server during a test. It does check that a compressed
response from an upstream server is correctly handled.

- 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.
