Description
Currently if GC, Quota, NamespaceController, ... experience problems when reading discovery we don't expose that information anywhere else than just in kube-controller-manager logs. We would like to go degraded with kcm-o when we know that either GC or quota is having issues. This should help identifying issues like "my namespace is stuck in terminating".
For this reason we want to expose the information about discover problems under /debug endpoint of kcm.
