Component settings are those that necessarily refer to a particular Deployment or Service. For example, the number
of Pilot replicas is a component setting, because it refers to a component which is a Deployment in the
cluster. Most K8s platform settings are necessarily component settings.
The available features and the components that comprise each feature are as follows:

| Feature | Components |

type clusterOrigin struct{}

	return "Cluster"
}

func (o clusterOrigin) String() string {
