Reports UMA data for bytes fetched over the network for used and
unused prerenders. It also reports on the total number of bytes
fetched for that profile since the last prerender report.
This gives us insight into the balance of used vs wasted prerenders.
Understanding the ratio of wasted prerender bytes to total bytes gives
us a better understanding of whether we need an option to disable
prerender on mobile networks.
