Description

The MonitoredRPCHandlerImpl refers to the params of a request, and will show them when we call 'toJson()'. But the running RPC call may be cleaned up and the ByteBuffer be released before the displaying in UI. We need to let the life cycle of RPC status monitor be inner the life cycle of RPC.
