   - @lvfangmin the `validateServerId` logic in `EphemeralType` is not a good place.
         e.g if the server which `myid=255` and her role is not the leader,it can create the
ttl node normally and 
     throw any exceptions. Really an issue. all logics which judge the myid should be put
in the start up of the server,I will fix this.
   - @phunt extend myid to 0, because 0 is also a valid number. lots of unit tests use the
myid=0, some of them are complicated.(e.g. assert the myid of the leader). it cannot just
use `i+1` to pass these tests. A headache,just do this to make jenkins happy.
