gluster-block: strict-o-direct should be on
Backport of https://review.gluster.org/18120
tcmu-runner is not going to open block with O_SYNC anymore
so writes have a chance of getting cached in write-behind
when that happens, there is a chance that on failover some
data could be stuck in cache and be lost.
