Remove the logic associated to the old transfer queue. A new transfer queue (gracefulexit_segment_transfer_queue) has been created for migration to segmentLoop. Transfers from the old queue were not moved to the new queue. Instead, it was still used for nodes which have initiated graceful exit before migration. There is no such node left, so we can remove all this logic. In a next step, we will drop the table. Change-Id: I3aa9bc29b76065d34b57a73f6e9c9d0297587f54
