* Added initial support for add/get/delete Flow state to the Network MAP via the REST API
  NOTE: The "add" REST API can't be used as-is.
* Added initial support for reading the Flow state from the Network MAP by the Controller
  and sending it to the switches.
  Currently, the Controller reads periodically the Flow entries (every 3 seconds)
  NOTE: The writing of the OpenFlow state to the switches is not tested.

The Python scripts for to add/delete/get flows are intentionally omitted until
the "add" REST API issue is resolved.

NOTE: Two new keys have been added to the database: "flow_id" and "flow_entry_id".
This requires that the older database should be deleted, because Cassandra
doesn't allow adding new keys to an existing database.
