Added new Flow-related API: clearFlow(), the REST "flow/clear/" API,
and the corresponding web/clear_flow.py Python script.
It is used to clear the flow state from the Network MAP,
but unlike the "deleteFlow() API, it does NOT push the deletion
of the flow entries to the switches.
It is needed to cleanup Network MAP state if somehow it becomes stale.
