HyperShift Operator manages per hosted cluster metrics dashboard

As a hosted cluster deployer I want to have the HyperShift Operator:

• Create a dashboard for inclusion in the OpenShift console that is populated with the key metrics for the new cluster
• Delete the hosted cluster metrics dashboard when a hosted cluster is removed

so that:

• I can determine the status and health of my hosted clusters over time
• Identify deterioration in the service
