    Fix volume throttling to Python 3

    BlkioCgroup._set_limits(): sort devices before iterating on them to
    have a reliable behaviour.

    The devs variable is a dictionary. On Python 3, the hash function is
    now randomized, so iterating on a dictionary gives items in a random
    order. Use sorted() to iterate on the list of sorted devices instead.

    tox.ini: add cinder.tests.unit.test_volume_throttling to Python 3.
