> While investigating config changes due to Ambari upgrade discovered few 
> potential issues around the support for default custom queue.
> # Ambari upgrade should not update custom queue properties. This is because 
> its unlikely to be invalid before Ambari upgrade.
> # All config properties related to the queue should be marked to not be added 
> during ambari upgrade. They all have defaults as "default"
> # Stack advisor should recommend only if the existing value for the queue is 
> invalid. Think of a scenario where user has explicitly set 
> "spark.yarn.queue"/"tez.queue.name" with a valid value and capacity scheduler 
> goes through an unrelated  config change
