Refactor the FlowManager addFlow() API:
 * It returns the FlowID on success, otherwise null
 * If the FlowID of the FlowPath is not set (i.e., its value is -1),
   the FlowManager will assign it.
 * Modified the web/add_flow.py usage to explain the value of Flow ID of -1
 * Removed method addAndMaintainShortestPathFlow() from the FlowManager,
   because it is not needed anymore.
