Consul-Conf: config templates from consul data

Object oriented mechanism to rewrite config files from template filled in by consul data.  The primary functionality here is to go through the consul services and nodes, using their health checks to come up with an idea of what nodes offer what servies  and their health status.  This data can then be plugged into  template to write out a configuration file. The code includes a diffing mechanism to verify that the file has changed, with comment exclusion, and hooks eg to restart services.
I was into the idea of 'just adding in the rspec task' but after 30 minutes of it goofing up my ability to include the consul mockup, I gave up.  If you're super into the idea of doing the same thing a different way, maybe we can work through it.
