- Refactor lfs request code - The original code uses `performRequest` function to create the request, uses a callback to modify the request, and then send the request. - Now it's replaced with `createRequest` that only creates request and `performRequest` that only sends the request. - Reuse `createRequest` and `performRequest` in `http_client.go` and `transferadapter.go` --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
