--------------------------------------------------------------
There are three ways to solve this problem:
(1) Call forceKillApplication on all sub cluster.
(2) Store secondary sub cluster when submit unmanaged application, then
forceKillApplication on these secondary sub cluster.
(3) forceKillApplication to secondary sub cluster when application is removed
in nodemanager.
Solution 1 is the easiest way. But we may call
forceKillApplication to unused sub cluster. And If we kill application to home
subcluster but not router, the app in secondary cluster will not be removed.
Solution 2: The problem is that NM will store the meta info of app. Router does
not know when NM store the info. So we must disable the cache.
Here I will choose solution 3. UAM is managed by NM, so this solution is most
reasonable.

> When AMRMProxy is enable, the application may allocate container among multi
> sub cluster. The application in secondary sub cluster will be labeled as
> unmananged application. When we run 'yarn app -kill \{appid}', the unmananged
> application will not be killed in secondary sub cluster.
> The unmanaged application will be removed util app attempt is expired after
> 15 minute.
