API Testing in a GUI

[pmcelhaney]

This is a big feature that I'm planning to add when I have time: a UI to test APIs, like Postman or Swagger UI, but tightly integrated with Counterfact.

This will be a great feature. Swagger UI is all well and good, but this ticket moves toward a UI that is tailored to what Counterfact is capable of such as proxying, toggling proxy per endpoint, showing the API mock code, etc. Exciting!
