Cinder Rally scenarios are failing on scale (wrong config)

create-from-volume-and-delete-volume and create-and-list-snapshots scenarios are failing on scale, with wrong configuration error:

I should mention, that fixing of these configs in the mos-scale repo should include unskipping them as well. They'll be skipped now.
