extension availability-zone v3 without alias as prefix for request params

[Alex Xu]

We need add alias as prefix for request params for v3.

    def server_create(self, server_dict, create_kwargs):
        create_kwargs['availability_zone'] = server_dict.get(
            'availability_zone')

    def server_xml_extract_server_deserialize(self, server_node, server_dict):
        availability_zone = server_node.getAttribute('availability_zone')
        if availability_zone:
            server_dict['availability_zone'] = availability_zone
