--------------------------------------------------------------

[~wilfreds]  [~eyang]  Have fixed remaining removal of isDebugEnabled and 
replace of commons-logging with slf4j. Have left some where the guard is 
necessary like multiple log lines, for loop, method calls inside. With this 
fix, the commons-logging can be completely removed (YARN-9364).  Can you review 
this when you get time.

> Follow up of YARN-9343 to address below review comments
> There are still 200+ LOG.isDebugEnabled() calls in the code. two things:
> There are a lot of simple one parameter calls which could easily be converted 
> to unguarded calls, examples:
> NvidiaDockerV1CommandPlugin.java
> FSParentQueue.java
> Application.java
> Some of the calls to LOG.debug that are guarded inside those guards have not 
> been changed to parameterized calls yet.
