[~leftnoteasy] and [~jlowe],

Thank you both for your reviews of this jira.

The previous patch did not handle all cases in hierarchical queues where the 
queue is over-capacity and some or all of it's children are non-preemptable.

This patch has been rewritten and should address all use cases.

> Disable preemption at Queue level
