// MockPreparedQuery is a fake endpoint that we inject into the Consul server
// in order to observe the RPC calls made by these HTTP endpoints. This lets
// us make sure that the request is being formed properly without having to
// set up a realistic environment for prepared queries, which is a huge task and
// already done in detail inside the prepared query endpoint's unit tests. If we
// can prove this formats proper requests into that then we should be good to
// go. We will do a single set of end-to-end tests in here to make sure that the
// server is wired up to the right endpoint when not "injected".
