Description
TestKeyValueStores currently resides in the samza-kv-leveldb module (after refactoring the original samza-kv - part of SAMZA-256)
This tests both LevelDB and the new In-memory store. Because of this samza-kv-leveldb has an additional unnecessary dependency on samza-kv-inmemory. We should move this test to samza-test, to get rid of this.
