Detailed Description
DataDelivery transfers data between specified physical locations.
start() must be called to start the delivery thread for processing DTRs and stop() should be called to stop it (this waits for all data transfers to exit). stop() is also called in the destructor.
All meta-operations for a DTR such as resolving replicas must be done before sending to DataDelivery. Calling receiveDTR() starts a new process which performs data transfer as specified in DTR.

Pass a DTR to Delivery.
This method is called by the scheduler to pass a DTR to the delivery. The DataDelivery starts the data transfer either using a local process or by sending a request to a remote delivery service, and then returns. DataDelivery's own thread then monitors the transfer.
Implements DataStaging::DTRCallback.
