Queue Producer Handler sends entire data model, should just send id

[Brandon Logan]

When sending messages over the queue to the controller worker, the api should just send the ids of the objects being created/updated/deleted. The queue producer handler is attempting to send an entire object.

    Fix queue producer handler to send ids

    Also renaming queueworker.py to controllerworker.py to be more
    obvious what it is. This patch should complete the api to queue to
    controller worker workflow (i.e. it should work).
