now that docker image is without a default value
(`spark.kubernetes.*.docker.image`), (yes that discussion is ongoing) I wonder
if it makes sense to bubble that up as a `--param` for visibility/convenient.
tbh I'm generally against adding `--param` to submit because of the
potential confusion it can cause, but since we are here and there's a
`--kubernetes-namespace`
