Secret replication accross clusters using ILB

[Krisztian-Molnar]

Dear maintainers of reflector,

This tool works like a charm within a cluster, it replicates our ElasticSearch secret containing certs to all of our namespaces where it's needed.
However it's only used on staging, because our production has a bit different setup: ES is deployed to another cluster, not where some of our apps are, and we use Internal Load Balancing to connect these apps from that different cluster to this ES.

Question: Would it be possible to somehow use ILB for replicating secrets to a different cluster, not only to different namespaces?

Thanks in advance!
