Add clickstream oozie job

This new oozie job runs monthly and by default stores its
resulting datasets in
for the computed month and wikis.
It uses the util/spark/submit subworkflow to launch the
scala application computing the datasets with a hive-context, and
the new oozie/util/loop workflow to loop over project list
to archive datasets.
