Separate out StorerFactory into its own interface. We had previously included a Factory and Destroy method in the Storer interface, but it makes more sense to separate those out into a StorerFactory interface. This lets us avoid the impression that we're using the same instance of a Storer for every test, separates the test methods away from the methods that are actually used in prod, and hides them from Godoc. What's not to like?
