When worked on ROS-only on-prem, we've created a dedicated ingress service with minimal functionality relevant only for ROS.

In the current stage, where we extend the chart with Cost Management components, we must use the RedHatInsights/insights-ingress-go

That ingress service is responsible for the processing of the payload and emit events that targets the cost-management topics.

The koku service that handles the event will be responsible to emit an event to ROS.
