Current benchmark picks destinations of RPCs in a random manner. However, it will result divergent benchmarking result because RPCs other than serializable range must be forwarded to a leader node when a follower node receives it. This commit adds a new flag --target-leader for avoid the problem. If the flag is passed, benchmark always picks an endpoint of a leader node.
