    Fix Image API 'versions' response

    Whether or not the v2.6 EXPERIMENTAL API is exposed at a site
    depends on the enable_image_import config value. If it's False
    (the default), then the API a client sees is the CURRENT v2.5
    API, and any of the v2.6 calls made against 2.5 return a 404
    (same as if you were running Ocata). This patch adjusts the
    'versions' response so that when enable_image_import=False,
    the EXPERIMENTAL v2.6 does not appear in the response.
