'Initializes the connection and returns connection info.
The  driver returns a driver_volume_type of \'fibre_channel\'.
The target_wwn can be a single entry or a list of wwns that
correspond to the list of remote wwn(s) that will export the volume.
Example return values:
.. code-block:: default
\'driver_volume_type\': \'fibre_channel\',
\'data\': {
\'target_discovered\': True,
\'target_lun\': 1,
\'target_wwn\': \'1234567890123\',
\'discard\': False
or
.. code-block:: default
\'driver_volume_type\': \'fibre_channel\',
\'data\': {
\'target_discovered\': True,
\'target_lun\': 1,
\'target_wwn\': [\'1234567890123\', \'0987654321321\'],
\'discard\': False'
