On Openshift clusters, CNO will expose a flag to deploy FRR-K8s.

MetalLB allows to interact with an FRR-K8s instance running on a different namespace.

The MetalLB operator must:

• detect that is running on openshift
• trigger CNO to deploy FRR-K8s
• instruct MetalLB to run in "external frr-k8s mode"
• not deploy frr-k8s itself

Consideration should be made for upgrade paths where MetalLB might already be deployed and functioning on a cluster and its FFR backend needs to be replaced with FFR-K8S deployed by CNO upon upgrade..
