Nginx: Start new span with kind client before proxying request #278
Description
What is the expected behavior?
To my understanding remote call spans should have span.kind: client. Currently this module only creates one span with kind server.
What is the actual behavior?
Create additional span with span.kind: client before proxying request.
Additional context
This can cause issues for tools which try to render a service map Grafana Tempo metrics generator for example. Technically there are other means to detect remote calls but client server spans are meant to serve that purpose.
