Cilium Feature Proposal

Is your feature request related to a problem?

Today is not possible to call services between clusters unless the Service resource and the Namespace are present in both clusters.
Describe the feature you'd like
Service foo residing only in cluster A should be able to call service bar residing only in cluster B without having to exist the Namespaceand Service of bar in cluster A.

Include any specific requirements you need

(Optional) Describe your proposed solution

Any time a global services is created/update the clusters running cilium should react and check if the service/namespace of theses services do exist in the local cluster, if not a new entry in CoreDNS should be created.
