Xiang Li 541f2e5200 etcdctl: support basic operations with etcd 0.4. ...

For CoreOS users, they will get a updated version of etcdctl without updating
the etcd server version. And the users cannot really control this behavior.
We do not want to suddenly break them without enough communication.

So we still want the most basic opeartions like get, set, watch of etcdctl2 work
with etcd 0.4. This patches solve the incompability issue.
