> 1. The RWQueueRpcExecutor has eight constructor method and the longest one has ten parameters. But It is only used in SimpleRpcScheduler and easy to confused when read the code.
> 2. There are duplicate method implement in RWQueueRpcExecutor and BalancedQueueRpcExecutor. They can be implemented in their parent class RpcExecutor.
> 3. SimpleRpcScheduler read many configs to new RpcExecutor. But the CALL_QUEUE_SCAN_SHARE_CONF_KEY is only needed by RWQueueRpcExecutor. And CALL_QUEUE_CODEL_TARGET_DELAY, CALL_QUEUE_CODEL_INTERVAL and CALL_QUEUE_CODEL_LIFO_THRESHOLD are only needed by AdaptiveLifoCoDelCallQueue.
> So I thought we can refactor it. Suggestions are welcome.
