 Our extrainfo descriptors have 15-minute intervals where we list the sum
 of bytes handled in that interval.

 Intuitively, it seems that congestion should have to do with how many
 times we run out of tokens in our token bucket.

 We could track the number of refills where our global buckets run dry, and
 publish the number of such refills in each 15-minute interval.

 We probably want to track read bucket and write bucket separately;
 differences between the two might teach us something about #4682 as well.
