Title: Allow container extensions to reach imports, parameters and services sections

I would like to write an extension to enhance the capability of "services" section, but current YamlFileLoader does not explicitly allow me to do that.

If a developer writes extension method `getAlias` as `return "services"`, he definitely wants to use this extension for "services" section and knows what he's doing. Why disallow that?
