cluster/dht: Optimize readdirp calls in DHT
Bring in option which is supported by posix xlator to filter out directory's entries from being returned. DHT would now request non-first subvols to filter out directory entries. dht xlator-option readdir-optimize will enable this optimization Change-Id: I35224bc81c9657f54f952efac02790276c35ded5 BUG: 838199 Signed-off-by: shishir gowda <sgowda@redhat.com> Reviewed-on: http://review.gluster.com/3772 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
