The cluster-network-operator needs to be HCP tolerations aware, otherwise controllers (like multus and ovn) won't be deployed by the CNO with the correct tolerations.

The code that looks at the HostedControlPlane within the CNO can be found in pkg/hypershift/hypershift.go. https://github.com/openshift/cluster-network-operator/blob/33070b57aac78118eea34060adef7f2fb7b7b4bf/pkg/hypershift/hypershift.go#L134
