    GlusterFS: Set permissions on qcow2 snapshot files

    The GlusterFS driver sets specific permissions on the
    volume file when volumes are created. Setting them on the
    snapshot files at snapshot creation time is also required,
    otherwise volume attaches will fail for volumes with snapshots
    when using QEMU's libgfapi functionality.

    This does not weaken the current security model in any
    significant way, as it only lines up the permissions used
    for snapshot files with those already used for volume files.

    This will eventually be addressed by functionality in libvirt:
