NBS is stable enough that we've made it the default store for command line tools, and the go-to store for tests that require temporary, but persistent, storage. We intend to remove support for LevelDB-backed chunk storage completely ASAP. This patch removes all usage of LevelDBStore from noms.git, but doesn't remove LevelDBStore _just_ yet as there are still some dependencies on it elsewhere. Toward #3127
