Add parameter attachment_history to FileAttachmentListResource
Review Request #10844 — Created Jan. 21, 2020 and submitted
The API of Review Board supports to upload another revision of an existing file attachment. Ideally to show changes to an image. This parameter allows is necessary to link to existing id.
Added an image, published draft and uploaded another image
with previous attachment_history. Saw that Review Boards
shows one file with two revisions.
