Monitoring data can now be stored in `metrics-*` patterns when collected through elastic-agent. [Our documentation](https://www.elastic.co/guide/en/kibana/current/monitoring-data.html) recommends to use the `monitoring_user` role to view the data in Stack Monitoring application but that role does not have permissions to read from the metrics pattern.

`monitoring_user` should be allowed the same permissions on `metrics-*` as `.monitoring-*`
