> In 3.7, Quota limit can be enforced and the quota related stats are captured 
> in the StatsTrack.  From the "listquota" CLI command, we can the quota limit 
> and usage info. 
> As an addition to that, we would like to collect the quota metrics and expose 
> them to the Prometheus for the following:
> 1. Monitoring per namespace (Chroot) quota usage via the Grafana dashboard
> 2. Creating alert based on the quota levels (e.g. 90% used)
