+ A new parameter, compute/compute_volume_common_az is introduced to
+ specify availability zone where tempest creates instances and volumes
+ for scenario tests, to allow us to run scenario tests in the deployment
+ which has multiple availability zones and cinder/cross_az_attach in
+ nova.conf is set to False.
