> In YARN-1885, there's a test in TestApplicationCleanup#testAppCleanupWhenRestartedAfterAppFinished.
However, we need one more test to make sure NM will do app cleanup when restart happens before
app finished. The sequence is,
> 1. Submit app1 to RM1
> 2. NM1 launches app1's AM (container-0), NM2 launches app1's task containers.
> 3. Restart RM1
> 4. Before RM1 finishes restarting, container-0 completed in NM1
> 5. RM1 finishes restarting, NM1 report container-0 completed, app1 will be completed
> 6. RM1 should be able to notify NM1/NM2 to cleanup app1.
