The packages option for spark submit is described
[here](https://spark.apache.org/docs/latest/submitting-applications.html) and
it seems to work. Using this option seems to be better alternative vs. then
spark.jars because makes more sense to download jars right inside driver and
executor pods, where they will be used. I think we may address this in a
separate PR because this could be useful for `yarn` cluster mode as well not
just for `k8s`.
