This is the lab of MIT 6.824 2018.

1. Lab 1 MapReduce hasn't test
2. Lab 2 Raft(raft.go):
   Set DebugMode to true while debuging to print debug logs.
   Outline of the API that raft expose to the service (or tester):
   1. rf = Make(...)
      create a new Raft server.
   2. rf.Start(command interface{}) (Index, Term, isleader)
      start agreement on a new log entry
   3. rf.GetState() (Term, isLeader)
      ask a Raft for its current Term, and whether it thinks it is leader
