1. Add a new boolean field in the Network CRD used by Cluster Network Operator (CNO) to determine whether to enable Network Observability. If the field value is true or the field is not there, it will enable it. If the field value is false, it does nothing. It never disables Network Observability or upgrades it. The management of Network Observability is still the responsibility of the Network Observability Operator (NOO).  Note: This is actually done in the openshift/api repository.

2. Add a new controller for observability in CNO. This leverages the existing CNO framework. The controller defines a Reconciler that tracks whether to enable Network Observability if it isn't already running.  "Enable" means to install NOO and create a FlowCollector custom resource.  This is done in the openshift/cluster-network-operator repository.
