sending nothing was keeping the connection alive.

We may use a different port in the config that is then mapped somehow.
But this should not affect where we try to contact remote nicknym servers.

This will get us more debug info in the logs if it happens again

http.rb does not do this on its own.

Allow queries by fingerprint (using keyservers to reply) and support key
lookup from other nickservers.

This is a major rewrite both in terms of our dependencies and our
architecture.  We moved the server and http_client from eventmachine to
Celluloid based libraries. This allows for a more concise syntax and
proper https handling.

In addition we now support ruby 2.3, use a Logger instead of stdout and handle
network errors properly

Turns out without this nickserver will not respond to multiple concurrent requests.
