The `instance` label is only useful if
- the exporter returns only data about its node or instance
- the exporter provides an instance label and then may return data about
other nodes
In this case, it's about the Prometheus mgr module, which is a single
exporter providing data about a whole cluster, so not only data related
to the node (or instance) the mgr module is running on. It is
completely irrelevant on which node the exporter runs on, the data
provided doesn't change. The exporter also doesn't provide `instance`
labels (which Prometheus wouldn't change due to our configuration, see
"honor_labels" setting).
(Actually there's one exception where `instance` labels are provided by
the Ceph mgr module, but that doesn't affect the Ceph Cluster
dashboard.)
Note that keeping that instance label on this particular dashboard would
enable the user to switch between a previously failed mgr instance and
the data collected from there and the currently running mgr instance (on
which the Prometheus mgr module runs on). That'd split the data, which
I don't think is a useful feature, but rather looks broken.

The health status widget doesn't show any status because it requires its
query to return a single result. But in case a mgr instance had failed,
it would return more, provided the incident has happened in the
requested time frame.
This is simply an issue of the `instant` switch being disabled for that
widget. As only one mgr instance can ever be providing data at a time,
enabling `instant` completely solves that issue.

Remove hard-coded timezone off Grafana dashboards to enable the Grafana
administrator to decide which timezone should be used for dashboards.
If we hard-coded those values, changing the global settings in Grafana
wouldn't have an effect. And the administrators can't change the
automatically imported Grafana dashboards provided by us.

The hosts-overview Grafana dashboard json file contains a repeated element, making
it invalid JSON. Some JSON parsers handle this. However, this prevents Jsonnet
from parsing the dashboard, which prevents the deployment of this dashboard via
Jsonnet.

In the AVG Disk Utilization panel, the result is calculated
by combining the output of node_disk_io_time_seconds_total
with the output of ceph_disk_occupation. However, the
first vector encodes the instance label with the full FQDN
while the ceph label only contains the hostname:port. In
order for these to match correctly, the domain name and port
has to be stripped from the labels.
