2 Collecting per-run data

Collecting per-run data is similar to collecting per-lease data, and relies on two methods in AccountingDataCollection: create_stat to create the stat in the probe constructor and set_stat to set the value of the stat. Given that per-run data summarizes information from the entire run, set_stat will usually be called from the probe's finalize_accounting method.
