Add support for multiple endpoints

[zacps]

I'm testing an application which has support for falling back to other endpoints. Because the server is known the API url never changes and isn't configurable.

I want to test that parts of the application will correctly fall back to other endpoints if they're configured. To do that I would need the ability to start additional mock servers with their own mocks.

@zacps would the solution proposed in #92 work for you? if so, we could look into implementing that.

Personally I'd say the solution proposed in #92 would fit nicely here. I'm also having that use case where I have multiple endpoints that are exclusively used in tests, such as mocking away an external service
