Watcher load balancing

[joaosilva15]

Feature request

Hello 👋 not sure if this is already possible but I would like to be able to configure the watcher to do GRPC client-side load balancing. This would make it easier to set up in Kubernetes as we would need to create a headless service and connect the watcher to it, instead of configuring a load balancer between the watcher and the API.

If this feature is already implemented, can you please point me to some docs on how to do it? I created the headless service and made the watcher have the same behaviour as with the normal service. Looking through the code I believe some GRPC configurations are lacking for this to be possible.

Thanks!
