ManagedClusterSet defines a group of ManagedClusters that user's workload can run on.
Put label cluster.open-cluster-management.io/clusterset=<clusterset_name>
on a ManagedCluster to assign it to a ManagedClusterSet.
To remove a ManagedCluster from a ManagedClusterSet, just remove the label cluster.open-cluster-management.io/clusterset
from the ManagedCluster.
User must have a RBAC rule CREATE
on a virtual subresource of managedclustersets/join
to add/remove label cluster.open-cluster-management.io/clusterset
to/from a ManagedCluster. In order to update this label on a ManagedCluster, user must have the permission on both the old and new ManagedClusterSet.
