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.
While I generally agree, especially around not optimizing for a situation in which we could just as well have kill -9 the thing, I'm going to do some local testing to see what orderly shutdowns look like.
