Add support for embedding cluster metrics

Problem to solve

We support the ability to embed project-specific metrics in markdown.

Currently, this ability does not yet extend to cluster health metrics, which can be managed on a project, group, or instance level.

Intended users

• Delaney (Development Team Lead)
• Sasha (Software Developer)
• Devon (DevOps Engineer)
• Sidney (Systems Administrator)

Further details

When managing an incident, a problem may be wider-spread than a single application. Users may want the ability to point to problems at their source.

Proposal

1. Add ability to link to specific cluster metrics charts via url
2. Include panel dropdown comparable to those on metrics dashboard
3. Add GFM handling to recognize the alternate route format for cluster metrics

Permissions and Security

Permissions for cluster health metrics can be tighter. Specifically, for an instance-wide cluster, only admins can view the cluster health metrics. Should we consider a shift in our permissions of embedded metrics to enable sharing of data?

Testing

What does success look like, and how can we measure that?

What is the type of buyer?
