Support Volume Num Weighter
Currently cinder support choosing volume backend according to
free_capacity and allocated_capacity. Volume Num Weighter is
that scheduler could choose volume backend based on volume number
in volume backend, which could provide another mean to help
improve volume-backends' IO balance and volumes' IO performance,
see details in ref [1] and [2].
