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
