We first need to determine the name of these namespaces, for both the staging and production releases.
For reference, Superset is deployed in the superset-next and superset namespaces, whereas Spark-History is deployed into spark-history and spark-history-test.
Usually, we try to make sure these namespaces match the wikimedia.org subdomain, so e.g. something like mpic and mpic-test/mpic-next, etc.
