Subject: [PATCH] [MINOR] stats: report the current and max global connection
 rates

The HTML page reports the current process connection rate, and the
"show info" command on the stats socket also reports the conn rate
limit and the max conn rate that was once reached.

Note that the max value can be cleared using "clear counters".
