make pluscloud open openstack-health-monitor results publicly accessible

[frosty-geek]

As pluscloud open,

we want our openstack-health-monitor results (see https://docs.scs.community/standards/certification/overview) to be accessible by the public without the need to be part of the SovereignCloudStack GH-Org or any form of requirement to register.

Public dashboards don't allow for any templating, so we'd need to do some hardcoding or create a public Org in grafana with a shared dashboard (with public credentials) if we don't want to lose the filtering capabilities (and the automated detection of what values are available for filtering).

The easy workaround is to create a user public with password plusserver inside the main organization with reader rights to the dashboards there.
I have done just that for gx-scs.
If that suits your needs, we can do the same for the pco grafana.
If you want, we can also publicly document the credentials.
