This is a repository type that would publish full files and the result of calling Conduit's phragment.queryfragments method to an S3 bucket, which ultimately reduces load on the Phabricator server (because clients can pull a JSON blob from an S3 bucket which scales far better than recalculating the result through PHP every request).

We now have to push full copies of files because the S3 backing store for files in Phabricator now stores things in chunks (and we want to offer full downloads to users directly).
