Comment:

 Ok scratch the above. So the issue is that we dump logs at every 5 minutes
 at info level now (introduced in c34411d9cb not yet released). That is
 fine.

 However, `rend_log_intro_limit()` has this snippet that upgrades the log
 to warning:

 {{{
   int exceeded_elapsed = (intro_period_elapsed > INTRO_CIRC_RETRY_PERIOD +
                           INTRO_CIRC_RETRY_PERIOD_SLOP);
   if (exceeded_elapsed) {
     severity = LOG_WARN;
   }
 }}}

 We shouldn't do that if we have not exceeded the limit of circuit creation
 in the first place (`exceeded_limit`). Exceeding the elapsed retry period
 is fine and actually expected sometimes because "network down" for
 instance.

 See branch `bug22032_031_01`.
