DSP-14176 publishing extra jars for Spark Job Server

Extras, python and api are published by:

export MVN_PUBLISH_REPO=abc
export MVN_PUBLISH_URL=xyz
sbt publish

Most of the dependencies from poms are removed since users should
use dse-spark-dependencies.

Main assembly artifact is published as it used be - no changes here.
