NIFI-548
This pull request shows a possible approach to support "FlowFile per
Datagram" for NIFI-548.
Most of the changes are for passing down a flag from the processor all the
way to the DatagramChannelReader which requires passing through a few levels of
classes.
The important change to the logic is:
* DatagramChannelReader - break out of the receive loop if null, or if we
only want one datagram
* UDPConsumerCallback - break out of writing to the FlowFile OutputStream
if we hit the totalBytes, or if we only want one datagram
