new AgeCounters()
A small helper object that counts into buckets the number of calls to its
bump that fall into three age categories; ages within an hour,
within a day or within seven days. Counts are maintained within the object,
and can be fetched to set into a gauge metric object.
This class is useful when exporting metrics that count the number of
hourly/daily/weekly active instances of various types of object within the
bridge.
