Apache augeas clean up (#9114)

The `# self.comment = comment` caught my eye while working on #9071 as well as the intermediate variables, which aren't really needed. As a result, I reformatted the code slightly in those places.

* Remove comment in AugeasCommentNode.__init__

* Replace some intermediate varibles with return-statements in apache augeas parser.

* more clean-up
