   I have added some metrics about stage in multiLeader:
   1. StateMachineLock: The time used to get stateMachine Lock for one consensus request.
   2. CheckWriteBlock(CheckBlock in picture above): The time used to check whether block write and wait for one request.
   3. WriteStateMachine: The time used to write a consensus request into stateMachine.
   4. offerQueue: The time used to offer consensus request into queue.
   5. totalWrite: Total time used to write a consensus request in main process.
   6. asyncConstructBatch: The average time used to construct a request in batch (div by the size of batch).
   7. asyncConsumed: The average time used to consumed a request in batch (div by the size of batch)
