Raw capacity pane in Host details dashboard in Grafana is always empty

[Yoshi Kadokawa]

Even after specifying a host that has OSDs (LP: #1982910), the Raw capacity pane is always showing empty result.

It looks like that the key name specified to collect from ceph_disk_occupation is not correct.[0]
At the moment, it is "instance", however after updating this to "exported_instance", the Raw capacity is shown correctly now.

Subscribing ~field-high since the key metrics in Ceph is missing.

Attached is the bundle that reproduces the issue.

This is the same for "Avg Disk Utilization" pane[0] in Host Overview dashboard.
It uses the same "ceph_disk_occupation" metric, and will require to query "exported_instance".

Please discard the comment on "Avg Disk Utilization" pane in Host Overview dashboard.
I double checked, and confirmed that this is not true.
