  - Apex: Change default verify scenario

    Since our default scenario os-nosdn-nofeature-ha is failing functest in
    verify, switch to os-nosdn-nofeature-noha which is passing. We want the
    lowest bar possible for initial patch set verification and then can use
    gate to verify more complicated deployments.
