nit: could we use something to detect grpc vs http even if this isn't set up for http yet? would make this reusable in the future.

AFAIU, resource detector is platform dependent on https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/processor/resourcedetectionprocessor/README.md#gcp-metadata

API type would need to be captured client side / added when introduced into the java storage client.
