Bug 8621 - Add shutdown-prefix-shard-replica rpc to MdsalLowLevelTestProvider

csit testing scenarios require clean shutdown of shard's local replica
funcionality. This introduces shutdown-prefix-shard-replica rpc to
MdsalLowLevelTestProvider. Upon invoking this rpc, local replica of
specified prefix-based shard is gracefully stopped.
