Address todo in compute cloud layer and move get_compute_usage to rely to the proxy layer. With this change method returns Usage object instead of munch. This also allows us to stop importing and inheriting from normalize class here. "attached" filter of the search_floating_ips is dopped since it is being pretty awkward.
