    Attachment: YARN-1446.1.patch

Upload a patch
- Add a new field in KillApplicationResponse to indicate the application is successfully Killed
- Change YarnClient.killApplication to wait until the application is successfully killed.
- Change application kill flow to kill the RMAppAttempt first, and let RMAppAttempt notify
RMApp that the app is killed, instead of kill RMApp before killing RMAppAttempt.

> When user kills an application, it should wait until the state store is done with saving
the killed status of the application. Otherwise, if RM crashes in the middle between user
killing the application and writing the status to the store, RM will relaunch this application
after it restarts.
