Update FlowManager's API design and define batch operation map's API.
- FlowManager returns FlowBatchHandle as a handler to the batch execution.
-- addFlow(), removeFlow() and executeBatch() methods are executed asynchronously.
-- Users can get the current state of the batch via the FlowBatchHandle.
- Defined FlowOperationMap's inital API designs.
This task is a part of ONOS-1687, ONOS-1842, and ONOS-1692.
