> Current k8s backend requires 3 separate container images to be provided by the user to submit an app. The 3 images are pretty much the same except for the entry point.
> Instead, we should require a single image by default, but still allow the user to override individual images (e.g. executor) if desired.
> This should also make it easier to publish an "official" Spark docker image, and should simplify things like the {{build-push-docker-images.sh}} script.
