The usage of Gateway API on an Openshift cluster can be measured by collecting how many Gateway Classes are created, which ones are Openshift managed or not (given controllerName "openshift.io/gateway-controller/v1"), and how many Gateways are created with each kind of Gateway Class.

kube-state-metrics can be used to fetch these counts, and a Prometheus rule can be used to aggregate these metrics and remove any specific information.

This way:

• Implement a kube-state-metrics configuration to collect the usage of GatewayClass and Gateway CRDs - This was already done by Dan Winship on https://github.com/openshift/cluster-monitoring-operator/compare/main...danwinship:cluster-monitoring-operator:gateway-metrics
• Implement a Prometheus Rule to aggregate the metrics - Done via https://github.com/openshift/cluster-monitoring-operator/compare/main...rikatz:cluster-monitoring-operator:gateway-api-telemetry

This story will be used then to register the current actions.
