feat: OTEL traces integration

[Villaquiranm]

alternative to #2434

Taking into account some of the reviews on #2434

I tried to integrate traces first on gRPC server. This already works on a basic form but we still need to identify important places were to put the traces

Added more traces direclty on rpc handlers
