MINOR: stats: Report max times in addition of the averages for sessions

Browse Source 
Now, for the sessions, the maximum times (queue, connect, response, total) are
reported in addition of the averages over the last 1024 connections. These
values are called qtime_max, ctime_max, rtime_max and ttime_max.

This patch is related to #272.
