Description of problem:

When hosted cluster is offline, this should be reflected in the cluster overview page if the ManagedCluster CR still exists.

1. We still show a "green" icon for node pools when the cluster is offline
2. Control plane should mention cluster is offline/unavailable (similar to the msg we already have above), based on the hostedcluster CR condition if it exists

Or we can simply remove this entire section if the cluster is offline?

Version-Release number of selected component (if applicable):
