If the driver creates two spark contexts shouldnt it use two different
spark confs with that property set up differently?
If no id is specified what will happen? I guess the dispatcher will not
know anything. What if you could use a unique id as aframeworkId plus an
increment, so the scheduler can detect all frameworks even the ones coming from
multiple contexts?
