> Currently, when submitting an application, storeApplication will be called for recovery.
However, it is a blocking API, and is likely to block concurrent application submissions.
Therefore, it is good to make application submission asynchronous, and postpone storeApplication.
YarnClient needs to change to wait for the whole operation to complete so that clients can
be notified after the application is really submitted. YarnClient needs to wait for application
to reach SUBMITTED state or beyond.
