> Right now, LLAP logs counters for every fragment; most of them are IO related and could
be very useful, they also include table names so that things like cache hit ratio, etc., could
be calculated for every table.
> We need to output them to some metrics system (preserving the breakdown by table, possibly
also adding query ID or even stage) so that they'd be usable without grep/sed/awk.
