Feature Request: override OTEL_SERVICE_NAME when using the observability feature

[v1v]

What

I want to override the default service name.

Why

So I can cerate my own set of service names according to my org's guidelines.

Further details

As far as I see OTEL_SERVICE_NAME is always set regardless if it's defined
