[ACM-10652] Added previously auto imported annotation to detached discoveredcluster

[dislbenn]

Description

When a DiscoveredCluster is automatically imported, we need to ensure that if the associated ManagedCluster is detached for any reason, we should not re-auto import the DiscoveredCluster back into the hub. To address this scenario, we are adding an annotation when the ManagedCluster is detached to ensure that the cluster is not imported again by default.
