Investigate if the consumer system could be merged into default Nuxeo.

Once we have a importer system that is split in 2 parts :

• one producer that does not depend on Nuxeo
• one consumer that handles the actual import part

Now the goal is to see if we could integrate the consumer part inside Nuxeo so that importing into Nuxeo becomes as simple as :

• contribute a Factory class (we will still need that to define the Document type mapping I guess)
• push data in a queue
