Thank you for your contribution, but I'm sorry to say that the development of OTLP-HTTP-Exporter has already been completed in 3442. However, due to the large amount of code, it was split into 2 PRs. The SDK part was merged a few days ago, and I haven't had a chance to submit a PR for the OTLP-HTTP-Exporter part yet, I will do it tomorrow.
