Web API: move content checksums under a common JSON key
Groups all computed content checksums under a 'checksums' JSON key (#779 (closed))
All computed content checksums are now grouped under a common JSON key when reaching the /api/1/content/<q: hash_type:hash>/ endpoint.
I have implemented this change on the service layer as other module clients could benefit from it.
