Before, the VA query was summing the total and dividing by the number of
rows. This gives the average bytes stored per hour, but we charge for
usage with byte-hours. Why not do value attribution the same way?
To do that, we don't divide by the number of rows. We also have object
and segment fees so return segment-hours and object-hours too.
