Task #5645: tracking: elephant flow detection
flowworker: heuristic to see how busy a thread is with elephant flows
Use the bit from #5647 to keep track of the ratio of packets belonging to elephant flows and non-elephant flows. Question is how to output it.
One way would be to have a set counter that tracks the percentage of eflow packets so they get into the stats log. When per thread stats logging is enabled it could show this per thread.
