Is your feature request related to a problem? Please describe.
We are using the Open Telemetry tracing feature of triton, however we are not able to configure the service.name of the exported traces.

Describe the solution you'd like
With most Open Telemetry SDKs the service name can be configured via the environment variable OTEL_SERVICE_NAME, see here. However when I tested this with triton the service name still was the default value unknown_service after I set the environment variable.

Describe alternatives you've considered
As an alternative the service name can be configured via a triton tracing config flag.

Additional context
The service name is a very important attribute of span, which allows to build a service graph and visualize the different services which are part of the trace.
