[SCSI] scsi_dh_alua: Add module parameter to allow failover to non preferred path without STPG
Resending with requested rewording of the parameter description. Currently
ALUA device handler sends STPG command during failover and failback. Failover
can be optimized by implicit failover (by not to sending STPG command), when 1
is passed as hwhandler parameter in multipath.conf. ex "2 alua 1". We may need
to pass the parameter through module param for alua device handler to optimize
failover if incase retain_attached_hwhandler set in multipath.conf and
hwhandler is set with non-tpgs device handler ex: '1 rdac'.
