    geo-rep: Disable xattrs and acls support with tar_ssh

    Geo-rep can't sync xattrs and acls with tar over ssh
    for following reasons.

    Issue 1: xattrs doesn't sync with tar over ssh.

    Reason: untar doesn't respect '--overwrite' option when used along
            with '--xattrs'. So it sends unlink if the file exists on
            destination and re-creates afresh. But all entry operations
            are banned in aux-gfid-mount as it may lead to gfid-mismatch.
            Hence fails with EPERM. This happens only when some xattr is
            set on a file in master volume.

    Issue2: acls on directories does not sync with tar over ssh.

    Reason: tar tries to opendir ".gfid/<gfid1>" and is not supported
            by gfid-access-translator as readirp can't be handled on
            virtual inodes and hence fails with ENOTSUP where as it syncs
            for files.

    Since the issue is with tar commmand it self and nothing could be
    done from gluster side, disabling xattr and acls support with tar
    over ssh option.

    Geo-rep can sync xattrs and acls with 'rsync' as the sync engine.
