python-cinder: Update cinder-volume initscript and postinstall

Cinder-volume requires the cinder-volumes volume group created.
The backing file for this volume is created in the postinstall
with a size of 2G on the first boot and the volume group is
created at boot time in the cinder-volume initscript.
