goflow-kube has a configurable flag to allow printing flows to stdout (see https://github.com/netobserv/goflow2-kube-enricher/blob/main/examples/goflow-kube.yaml#L69 )

In the operator, this is currently turned off and not expose through the custom resource.
We should keep it off by default (for performance) but however allow to turn it on for debugging / testing purpose.
That would be a new field in the "goflow-kube" section of the CR: https://github.com/netobserv/network-observability-operator/blob/main/config/samples/flows_v1alpha1_flowcollector.yaml#L10
