Dashboard: Change default refresh interval

Previously the default refresh interval when opening a dashboard was 1 minute but now it is set to not refresh at all. Not sure when this changed but it was fine in at least 1.5 and likely 1.6 but not in 1.8.0 and 1.8.1.
Is there somewhere to change this and the default time range?

Thanks fredricj , this was probably result moving to Grafana Plugins, so we’ll bring them back in https://jira.percona.com/browse/PMM-2227
