Description

1. Separate EventLoopGroup between dataserver and control client/server, as the node which is busy on receiving data from different nodes may occupy all EventLoopGroup threads, will block the control rpc message, e.g. fragment transfer.
2. Change the default threads of EventLoopGroup to 8(current is 10), as it can improve performance if the number is power of two based on PowerOfTwoEventExecutorChooser of Netty.
