Nova has a legacy hack to allow admins to specify hosts via an
availability zone using az:host:node. That means ':' cannot be
included in the name of an availability zone itself.
However, the aggregate API accepts requests which have
availability zone names including ':'.
This patch checks the availabilty zone name when aggregate is
created or updated and raises an error if it contains ':'.
