  - Remove No Longer Needed 'archive-repositories' Job

    This job was written for Scott Winslow to easly pull in a tarball of all
    the OPNFV source code to do license scanning. As Scott notified us he'll
    be running the job himself from now on, we can remove it from the OPNFV
    Jenkins system.
