Make use of the new srv->rid value in stats. Stat is referred as ST_F_SRID, it is now used in stats_fill_sv_stats function in order to be included in csv and json stats dumps. Moreover, "rid: $value" will be displayed next to server puid in html stats page if "stats show-legend" is specified in the stats frontend. (mouse hovering tooltip) Depends on the following commit: "MINOR: server: add srv->rid (revision id) value"
