### Description of PR
JIRA: [YARN-11644](https://issues.apache.org/jira/browse/YARN-11644)
LogAggregationService can't upload log in time when application finished.
Current implementation of AppLogAggregatorImpl is to do empty while loop
until application finish.
If too many applications running, it will block the following applications
upload logs.
Make AppLogAggregatorImpl return when application has not finished and
resubmit itself to thread pool. It not only fixed the block issue but also
shrink the thread pool size (default: 100).
