Code Issues Proposed changes

Update FC connection_properties examples

Browse Source 
This patch updates the FC examples that we have in the code in the
connect_volume method docstring to reflect the support of different
target luns and the new enable_wildcard_scan key.

For FC the dictionary could also present the enable_wildcard_scan key
with a boolean value (defaults to True) in case a driver doesn't want
OS-Brick to use a SCSI scan with wildcards when the FC initiator on
the host doesn't find any target port.
This is useful for drivers that know that sysfs gets populated
whenever there's a connection between the host's HBA and the storage
array's target ports.
:param connection_properties: The dictionary that describes all
of the target volume attributes.
