In Federation, kill application from client does not kill Unmanaged AM's and containers launched by Unmanaged AM

In Federation, killing an application from client using "bin/yarn application -kill <application_id>", kills the containers only of the home subcluster, the Unmanaged AM and the containers launched in other subcluster are not being killed causing blocking of resources.

The containers get killed after the task gets completed and The unmanaged AM gets killed after 10 minutes of killing the application, killing any remaining running containers in that subcluster.
