Feature/hacking consul file config (#157)

* moving things around to see if I can get consul to store fileconfiguration rather than ocelotconfiguration

* more refactoring to see if we can get a test for the feature

* acceptance test passing for updating in consul..need to sort object comparison out

* fixed the failing tests
