Sending custom headers with apache-airflow[otel]

[ninad-opsverse]

I am running the AWS Apache Airflow instance locally using aws-mwaa-local-runner.

I am configuring the airflow configuration file (airflow.cfg) for sending metrics to a specific otlp endpoint (I have an open telemetry collector instance running in a kubernetes cluster). I have configured the metrics section as follows

[metrics]
otel_on = True
otel_host = <my_otlp_endpoint>
otel_port = 4318
otel_ssl_active = False

I need to pass the Basic auth via headers. But I dont see an option for passing custom headers in the metrics specific configuration options.

Is there a way to send custom headers for the above mentioned purpose?

I'm also interested in this.

So maybe someone would like to contribute it if there is no other option? @ninad-opsverse @Kludex ? I have no idea if it's possible but deep dive in the code should give the answer and maybe it would be good to add such feature.
