Make it possible to get the metadata of a single attachment from the REST endpoints

Calling .../attachments returns array of attachments metadata like the json below. But, when calling .../attachments/{fileName}, the response is not a json object, but the file binary content and the mimetype.
As a REST client, one needs to fully download the file, which is not optimal, and re-compute all the of the metadata that one could get from the server, which is not optimal either.
The only other option is to call the .../attachments REST endpoint. But this is not optimal either as the list of attachments is not paginated and cannot be filtered.
