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.
This class is so-named because it should only run on the leader. Appears after this change that even slave Singularity will start up and run these guys.
