>             Project: ZooKeeper
>          Issue Type: New Feature
>          Components: metric system
>    Affects Versions: 3.7.0, 3.7

> 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)
