[Tomoki Sekiyama]

When "image_upload_use_cinder_backend = True" is specified to the volume backend, and the Glance cinder store is enabled, upload-to-image command fails with the following error.

This is due to unnecessary attributes specified in the volume creation params, such as '' or 'volume_attachment' or 'consistencygroup'.

    Fix image volume creation error

    When "image_upload_use_cinder_backend = True" is specified to
    the volume backend and the Glance cinder store is enabled,
    upload-to-image command fails with the following error:

      Create clone_image_volume: xxx for image xxx failed
      (Exception: An object of type VolumeAttachmentList is required
       in field volume_attachment, not a )

    This is due to unnecessary attributes specified in the volume
    params, such as 'volume_attachment' or 'consistencygroup'.
    This patch removes the unnecessary attributes from the params.
