follow more closely the official OTEL recommendations, and also try to reduce global state. - use a class type for `Exporter.t` (instead of 1st class module `backend`) - have tracer, logger, metrics_emitter as explicit objects - keep a `Main_exporter` to make migration easier, but discouraged - add stdout_exporter and debug_exporter to opentelemetry.client
