Install Group runner on group-level cluster
Problem to solve
Current k8s integration installs a project-level runner. For group-level cluster, the integration will need a group level runner.
Group level runner will allow multiple projects to leverage it.
When installing "runner" app on group level cluster, a group runner should be provisioned.
What does success look like, and how can we measure that?
(If no way to measure success, link to an issue that will implement a way to measure this)
