Feature/automatic routes with sd (#351)
* #340 started looking at supporting automatic routing when using service discovery * #340 getting old routing tests to pass * #340 renamed stuff to provider rather than finder, as its not longer finding anything * #340 working towards supporting dynamic routing * #340 loads of refactoring to make configuration work with dynamic routing * #340 refactor consul config code so the registry class owns it * #340 default to consul to maintain backwards compat * #340 added docs, finished this branches todos
