> Add ReadWriteLock into PipelineStateMap to protect contentions between RaftServer and PipelineManager.
> If current leader SCM (as leader of term N) step-down while there are on-going transactions, there might be read/write contentions that new leader SCM (as leader of term N+1) is replicating raft log entries encapsulating method addPipeline/removePipeline/updatePipelineState to underlying RaftServer which will be applied by StateMachineUpdater, and at the same time PipelineManager is calling getPipelines.
