TODO

-* Fix file middleware to use a proper zone implementation
-    * Zone parsing (better zone impl.)
-* Zones file parsing is done twice on startup??
-* Cleanup/make middlewares
-    * Fix complex rewrite to be useful
-    * Healthcheck middleware
-    * Slave zone middleware
-    * SkyDNS middleware, or call it etcd?
-* Fix graceful restart
-* TESTS; don't compile, need cleanups
-* http.FileSystem is half used, half not used. It's a nice abstraction
-    for finding (zone) files, maybe we should just use it.
-* prometheus:
-    * track the query type
-    * track the correct zone
-
-When there is already something running.
