> When we take snapshots, a copy of snapshot file and its MD5 file are persisted on disk. But they are not atomic operation. In some condition, we might have a partial snapshot file persisted on disk. While we need to SimpleStateMachineStorage#findLatestSnapshot(), we should skip the snapshot files without MD5.
