Show cluster status to users without permissions

We currently don't show the Cluster option in the navigation for users without Master permissions.

This proposal lets those users see some basic information in the page:

  • Users without permissions can only see cluster integration status and the cluster's name.

  • If cluster integration is not set up for the project or it's not a GKE cluster, the cluster name field is not displayed.

  • In all cases the HTML element for the switch is disabled and cannot be interacted with.
