Adds test for /server resource

[derekr]

Initial stab at adding basic integration tests. Currently this only tests the /api/server* route by checking for a 200 ok response from thoth-api and that the response object from thoth-index is flattened.

{ response: { numFound: 0, start: 0, docs: [] }

would be

{ numFound: 0, start: 0, docs: [] }

Let me know if my assumption of the thoth-index response handling is correct.

The tests are generic enough that you could run against an actual running thoth-index and not change the port to 3002 as the readme suggest.

Convention

Integration tests would go under /tests/integration and naming the resource w/ the request type being tested.
So testing a GET request against the /api/server* resource would be /server-get.js.

Modules

Using tap for testing because it's super simple. Added request to simplify the request handling in tests, though it might be worth looking in to using request instead of http in the dispatcher modules.

hey @derekr what would t be? can you use a more explicit name? (or is this a convention?)

ah, nevermind. I just read about the tap module
