docs: A convenience method that creates a ServletConfig object. This also populates
  the necessary metaData which enables the Servlet associated with the returned
  config to correctly lookup NameSpace entries. It is highly recommended that
  extension processors use this method to create the config objects for the targets
  that the processor creates.
