[SPARK-25220] Seperate kubernetes node selector config between driver and
executors.
Seperated node selector config option between executors and driver.
This removes the spark.kubernetes.node.selector config option and seperates
it to
spark.kubernetes.driver.selector and spark.kubernetes.executor.selector
to allow seperate node selectors on drivers and executors.
My personal use case for this change is that on AWS we have cheap
spotinstances that can terminate at any moment which is okay for executors but
not the driver.
With a single node selector option I am unable to use the spot instances to
save costs on the executor nodes.
