## What changes were proposed in this pull request?
Add ability to map the spark resource configs spark.{executor/driver}.resource.{resourceName} to kubernetes Container builder so that we request resources (gpu,s/fpgas/etc) from kubernetes.
Note that the spark configs will overwrite any resource configs users put into a pod template.
I added a generic vendor config which is only used by kubernetes right now. I intentionally didn't put it into the kubernetes config namespace just to avoid adding more config prefixes.
I will add more documentation for this under jira SPARK-27492. I think it will be easier to do all at once to get cohesive story.
## How was this patch tested?
Unit tests and manually testing on k8s cluster.
Closes #24703 from tgravescs/SPARK-27362.
