[jira] [Created] (ZOOKEEPER-4211) Expose Quota Metrics to Prometheus

Li Wang created ZOOKEEPER-4211:
----------------------------------

             Summary: Expose Quota Metrics to Prometheus
                 Key: ZOOKEEPER-4211
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4211
             Project: ZooKeeper
          Issue Type: New Feature
          Components: metric system
            Reporter: Li Wang


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)
