Allow to access remote archive

This is Workhorse part of https://gitlab.com/gitlab-org/gitlab-ee/issues/2619

Allows extracting individual files from externally stored ZIP archives by using Content-Ranges as described here: https://gitlab.com/gitlab-org/gitlab-ce/issues/29203#note_30198233.

This MR adds vendor for the needed httprs, but also includes changes introduced by patch.

Thanks @ayufan, a few questions. I'm impressed by how easy it is to support this!
