    Use get-pip for pip installation

    Changes in devstack and nodepool will allow for pre-cached get-pip
    script to be used, instead of downloading from the internets. Enable
    the flag so that the cached script and the local mirror will be used
    for pip installation.

    Closes-Bug: #1254275
    Change-Id: Ia5f69073f7f9bab9b5554185df5681fbd178b91d

https://review.openstack.org/58099 is still open (and in WIP status), so get-pip.py is getting downloaded, sometimes poorly, leading to execution failures.

This has been resolved in a couple of ways. First we cache the install pip script on all of our slave images. Then devstack was updated to use that cached script if it is available. You can see the devstack change at https://review.openstack.org/#/c/97912/.
