Description of problem: Right now we want to use tcmu-runner alua feature for setting priority path (not the path switch and failover). But the ALUA code in tcmu-runner is supported for handlers which support lock routine. We need to make changes to allow glfs handler which is missing lock routine to take advantage of prio path setting logic. This is needed by load-balancing feature in gluster-block.
