Okay, so this means if req_spec.avz is None, this holds -> "None, which means that the instance can move from one availability zone to another during its lifetime if it is moved from one compute node to another."
Since the default before Pike if the avz was not specified is None, we will go ahead with an online_migration tool to populate instance.avz if its None.
