    Description

      YARN-9537 added a feature to disable AM preemption on a per queue basis.

      This is a nice enhancement, but it's very inconvenient if the cluster has a lot of queues or queues dynamically created/deleted regularly (static queue configuration changes).

      It's a legitimate use-case to have AM preemption turned off completely. To make it easier, add property which acts as a global flag for this feature.
