Move cinder scheduler to where volume is located

HA failover causes cinder-volume to stop responding because the
scheduler does not reconnect properly after the vip failover. Since the
scheduler is worthless w/o the volume service anyways, just put it right
there  where the volume is and off of the ha controller 1/2 nodes.
