This fixes #50 by periodically resetting the prometheus counters to keep the cardinality in check.
Even though that mitigates the issue greatly, it requires tweaking
Metrics.resetPeriodMinutes
(depending on your traffic).So I still decided to disable high cardinality metrics by default in order to keep the rest of the metrics working (and protect people's privacy) by default.
