This commit drops the Storage interface and just replaces it with a publicized TieredStorage type. Storage had been anticipated to be used as a wrapper for testability but just was not used due to practicality. Merely overengineered. My bad. Anyway, we will eventually instantiate the TieredStorage dependencies in main.go and pass them in for more intelligent lifecycle management. These changes will pave the way for managing the curators without Law of Demeter violations.
