Just tried the `vanilla` (so without this #2637 PR) zeppelin on spark-k8s
with the `in-cluster client mode` branch
(https://github.com/apache-spark-on-k8s/spark/pull/456).
It works fine out-of-the-box (with the ad-hoc spark interpreter parameters).
@matyix Do you see any reason to further work on this PR? Maybe you want to
address additional goals with this?---
