    Fix image from volume upload ERRORs and WARNINGs with Ceph RBD

    By resetting image_upload_use_cinder_backend to upstream default.

    When uploading volume to glance image, cinder looks at the backend's
    image_upload_use_cinder_backend config knob to decide whether to try link
    the glance image to a cloned volume made by cinder, i.e. by doing all work
    locally and only updating glance's locations for the image (when the knob
    is set to True). However, after all [1], [2] and [3], which happens since
    Victoria, this option requires further config from user (using volume type
    with image_service:store_id property (aka extra spec) set to the desired
    glance store (even if there is only one cinder store configured).

    Please read the bug report as to why the option removal is the
    best option (TL;DR it is the most compatible approach).
