The grand Guice injection fixup

This branch will get all the Guice changes to make DI work correctly and eliminate all the race conditions and have the startup and shutdown of the service controlled by the dropwizard framework.

The first patch is fixing all the lazy injection places, add explicit injection for everything that is referenced through Guice and uses eager injection everywhere.
I am not sure that doStop still exists in DW 0.7. The Server cli command creates the server on the fly and then calls `server.stop()` when shutting down. The right thing would have access to this server object and call `stop()` on it. Might need some digging; leave the comment, we can fix that later.
