Basic authentication for opentelemetry output

Use Case

I've setup OTEL collector to listen on gRPC with basic authentication but there's no option to do so for telegraf's opentelemetry output. Is it possible to add basic authentication to telegraf's opentelemetry output?

Expected behavior

Unable to send metrics to OTEL OTLP that use basicauth extension.

Actual behavior

N/A

Additional info
