TiKV has two types of kv API(txn and raw), both of them can scan reversely,
Txn KV: reverse kv_scan is available from v2.1.0-beta,
Raw KV: reverse raw_scan is only available on master(30251412). Because it is an experimental feature.
Please consider upgrade to TiKV v2.1-rc if you want reverse kv_scan.
