    gate fixer: Fix devstack auth issue and new PEP8 violation

    Squashes two commits needed to unblock the gate:

    devstack: prevent auth params set in env. polluting client calls

    The switch to keystone v3 has introduces issues when other devstack
    components set tenant or project name in environment, as it overrides
    those set by us in our plugin script. This ensures that doesnt happen.
    It also updates usage of upload_image to avoid issuing a token (no longer
    needed) and uses openstack client to create the nova flavor using clouds.yaml.

    Fix E402 pep8 violation
