When the connector wants to use multipath, multipath=True should be
specified. If enforce_multipath=True is specified too, an exception is
thrown when multipathd is not running. Otherwise, it falls back to
multipath=False and only the first path shown up is used.
For the compatibility reason, even if multipath=False is specified,
some cinder storage drivers may export the target for multipath, which
can be found via sendtargets discovery.
