    Set the correct variable in run-upgrade.sh

    In run-upgrade.sh we are creating a temporary variables file that is
    intended to be deleted post upgrade. We were setting the wrong variable
    for the intended purpose - we want to allow containers to talk directly
    to the repo containers since users will not be able to configure their
    LB ahead of time.

    By setting openstack_repo_url, we get the same effect and then we also
    need to set the scheme (http://) appropriately so pip-link-build.py
    appropriately sets up trusted-hosts in pip.conf
