mod_prometheus: Invoke stats collection if in 'manual' mode
Since 10d13e0554f9 a special value for statistics_interval "manual"
exists, where a module is expected to invoke processing in connection to
collection of stats. This makes internal collection and exporting to
Prometheus happens at the same time with no chance of timers getting out
of sync.
