:bulb: [Feature] Create new Grafana dashboard for long-term metrics

[huard]

Description

#542 Adds new metrics for reporting platform usage statistics. It would be nice to have a custom dashboard to visualize those metrics.

References

Prometheus assumes that measurements are "stale" after 5 minutes. Hourly averages or rates are thus shown in graphics over 5 minutes intervals separated by empty gaps. One solution to "fill the gap" is to run the expression last_over_time(<metric>[1h]) to connect those points together.

If we find that Grafana is not adequate to report long term metrics, we could use the Prometheus API to get the raw values, flip them into a DataArray and display them in a notebook. If the objective is to include tables and figures in reports, maybe this would be preferable.
