Dropwizard - Quartz Integration (Issue #797)

This PR is related to Issue #797. If after looking it over there is a desire to make this an official DW module, I can move things around and issue a new pull request over there. 

As you can see the Quartz integration was done using Bundle, Managed, and a couple of Tasks to get things started. The tasks are useful for suspending Quartz jobs without having to write any custom endpoints in REST to do the work. Likewise, the simple reporting task can give a quick view into what the job queue looks like in JSON.

I'm open to expanding it further if there is interest in the code. Just let me know.

There are also a number of unit tests as well included in the PR.
