Show Kubernetes cluster used for deployment
Problem to solve
Group clusters now make it harder for a user to know which cluster was deployed to.
This is a general issue - see also https://gitlab.com/gitlab-org/gitlab-ce/issues/55094
Show the cluster deployed to in the CI job page. For example:
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)
