Merge ~lihuiguo/charm-grafana:bug/1928759 into charm-grafana:master

[Linda Guo]

show multiple ceph pools at once

the Grafana ceph pool dashboard shows per-pool metrics,
    but there's no way to see multiple pools at once.
    We would like to be able to see multiple pools stacked
    to be able to visually determine which pool is using up the most IOPS
