Add PodSpec to JopManager and TaskManager

[ls-1801]

Hello,

I want to specify a schedulerName and a priorityClassName for the TaskManager Pod.

I am creating a new scheduling framework for my bachelor thesis when implementing support for the Spark-Operator. I find it very convenient to have the PodSpec be part of the Executor/Driver pod.

I guess I could also implement the feature by creating a new BatchScheduler. Let me know if extending TaskManagerSpec and JobManagerSpec with a PodSpec (and thus also moving nodeSelector, labels, annotations, tolerations) sounds reasonable. Otherwise, I might go the BatchScheduler route.

Hi @ls-1801 Sorry for late reply.

Adding a PodSpec sounds interesting and I think it's worth exploring! Do you still have time to propose something?
