  - xci: osa: switch back from GitHub to OpenStack OSA repos

    Switching to github.com for the gitclones did not make much of a
    difference since we are still seeing randomg SSL failures during git
    clones. So we can switch back to git://git.openstack.org hoping that
    the git protocol will be more efficient than https. Moreover some
    projects are moving away from github mirroring and this breaks our
    tests.
