Allow separate images to the specified for Hosted Control Plane components

Hypershift needs to be able to specify a different release payload for control plane components without redeploying anything in the hosted cluster.

ovnkube-node DaemonSet pods in the hosted cluster and the ovnkube-master pods that run in the control plane both use the same ovn-kubernetes image passed to the CNO.

https://github.com/openshift/hypershift/blob/fc42313fc93125799f7eba5361190043cc2f6561/control-plane-operator/controllers/hostedcontrolplane/cno/clusternetworkoperator.go#L90

We need a way to specify these images separately for ovnkube-node and ovnkube-master.
