yea，according to raft paper, a leader should step down and become follower
if it discovers any server with a higher term.
but, i am not quite clear that is it necessary if the discovered server has
a less up-to-date last logEntry? or will there be any problem if the leader
does not step down to follower when it finds the raft peer , with a higher
term, has a less up-to-date last logEntry?
i would like to hear your views. @szetszwo @kaijchen
