Create Releng Job for Generating Artifact JSON API

'opnfv.org/artifacts' uses the index.json file generated by the
opnfv-artifacts.py script to list artifacts generated
by other OPNFV builds.

This adds a Jenkins 'cronjob' for generating and uploading a JSON file
to Google Storage containing links to the artifacts and their metadata.
