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'.
