Add support for Dropwizard reporter config registration #9
Description
Based on these two docs:
http://www.dropwizard.io/0.8.0-rc1/docs/manual/configuration.html
https://groups.google.com/forum/#!topic/dropwizard-user/UTEPCilA_I0
It looks like we should be able to make the NewReplicReporter accessible via the metrics YAML block in Dropwizard configuration.
