Backstage cluster details page linking to cluster overview dashboard

[Rotfuks]

Motivation

Currently in the Cluster Overview Page we link to the Dashboards Overview in Grafana. Now that we have a managed Cluster Overview Dashboard that can serve as a nice entrypoint to the observability platform we should rather link to this then the more broad and general dashboard overview, where people might be a bit lost in the beginning.

Todo

• Replace the "Dashboards" Link in the cluster overview (ie: https://devportal.giantswarm.io/clusters/gazelle/org-giantswarm/gazelle) to a "Cluster Overview Dashboard" Link leading to

grafana.<BASE_URL>/d/gs_cluster-overview/cluster-overview?orgId=1&from=now-6h&to=now&timezone=browser&var-datasource=default&var-cluster=<CLUSTER_ID>

• Optional: Could we maybe also get the :observability-bant: logo as the link icon instead of the grafana logo? That would be awesome :)

Outcome

• Customers will directly jump to the Cluster Overview Dashboard when navigating from the Cluster Overview in their Portal, getting a better "red-line"-User Journey from the Portal to the Observability Platform

Roughly like this:

We should provide a little more horizontal space per link so that the labels take two lines instead of three.

Updated the targetlink with a new semantic Id of the dashboard that will be rolled out with the next release of dashboards.

@Rotfuks I think the observability bant (which I know only from Slack) doesn't fit that context very well. All our icons in the UI are monochrome and vector. Apart from that, I think they are hard to interpret by customer users.

@Rotfuks I prepared a PR with the changes. Please let us know when the new dashboard is released so we can also release our changes. Thank you.

[Rotfuks]

The dashboards with the new non-random ids are rolled out. So you can release your changes, @gusevda! Thanks

@Rotfuks released and available on Devportal.

This is awesome! Thank you!

Is the dashboard not rolled out yet to customers? I tried one customer cluster (not naming it here), and it failed to find the dashboard.
