Comment 4 for bug 1982712

Agreed - I think the snap install and configuration of the required user should happen when its required - i.e. when the charm is related to either Prometheus or Nagios.

Neither operation will be impacting on MySQL (i.e. no restart required) so I think this is fine.

It means if the charm is not monitored, we don't incur the load of the exporter or the increased security attack surface of another network endpoint and the user in MySQL.
