Change FlowBatchHandle to be interface class.

- Users can access to the shared flow batch operation map
  using the FlowBatchHandle.
- FlowBatchHandle is an interface and the instance of it
  can be obtained from APIs defined by FlowManagerService.
- The implementation of the map can be accessed only from
  the implementation of the FlowBatchHandle.
- This task is a part of ONOS-1692 and ONOS-1842.
