Diff File Attachment Resource

Provides information on file attachments associated with files in diffs.

The list of file attachments are tied to files either committed to the repository or proposed in diffs to a review request on the repository. All are associated with a file in a diff.

Files that are newly introduced in a diff and do not have a revision as of that diff will have the added_in_filediff link set, and repository_revision will be null.
