gifs/api: datastore_test.go diff

Spike out functionality and tests. Create our interfaces around storing data and retrieving it. Create an in-memory implementation of our interfaces, for testing and rapid dev purposes. Begin sketching out what our unit tests look like. Create our Google Cloud Storage datastore implementation. Sketch out an idea for a usage collection process to keep track of which users are actually using stuff.
