Craig Condit updated YUNIKORN-1464:
-----------------------------------
Description:
To support preemption, we need to add the following queue properties:
* preemption.policy - string \{ fence | default | disabled}
** Whether to allow victim selection for preemption to propagate upwards to
parent queues (default) or not (fence). Preemption can be completely disabled
for a subqueue with "disabled".
* preemption.delay: string (duration, default: "30s")
** How long a task must be waiting before preemption will be considered
** Must evaluate to > 0
