In Tacker, we now are fixing Tacker scaling to fully leverage heat-translator.
To make a best fit, Tacker need to have nested resources from heat-translator.
Heat-translator already provided this by using translate_to_yaml_dict().
Unfortunately, this method always return to the main heat yaml file not to
nested yaml file.
