Cleanup in the FlowPusher and the FlowSynchronizer:
 * Don't use FlowPath and IFlowPath when pushing flows through the
   FlowPusher, because it is not needed anymore: now the FlowEntry object
   is self-contained.
 * Removed the alternative FlowPusher add(IFlowEntry) method that takes
   IFlowEntry argument from Titan; instead, extract the IFlowEntry
   into a FlowEntry object, and then use the remaining add(FlowEntry)
   method.
