Feature description

As it right now, we are creating a Route object for every InferenceService instance we deploy in a Project. That can lead to serious performance issues.

We are working with the model serving team to adapt the controller for this specific scenario:

1. When a Serving Runtime is created in a namespace, the odh-model-controller will create a route with a deterministic name based on the namespace (project)
2. Each time we create a new inference service, it will add a path with a deterministic format if external route is enabled.
3. This logic will be available for both inferenceSErvices already deployed and new ones.
4. For existing inference services, the old route will be available in case it's being used for production.
