THe command used to start the service is:

/usr/local/bin/opentelemetry-instrument --service_name pulp-content --exporter_otlp_endpoint http://pulp-otel-collector-svc:4318 --exporter_otlp_insecure true pulpcore-content --access-logfile -

I am seeing these items being repeated in my oci-env too:

An instrument with name http.server.duration
An instrument with name http.server.active_requests

Are not these the defaults coming from the aiohttp instrumentation?
