Dual-write for KAS
As per our discussion during the team sync on 30.X.2023, we would like to set up dual-write for KAS team. They should send traces to both our old infra (jaeger+jaegerclickhouse) and new infra(Gitlab UI+otel collector).
This will enable Mikhail to evaluate the new Gitlab UI better by seeing his own data in there and for us it will be intermediary step before we we try to push traces from the SaaS instance.
