Description

Hi,

I'd like to see whether we could enhance the current Spark 2.4 on k8s support to bring in the `PodPriority` feature thats available since k8s v1.11+

https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/

This is helpful in a shared cluster environment to ensure SLA for jobs with different priorities.

Thanks!

Li
