Title: rose config_cli: style changes

Style changes made as follows:
* NoMedata event added
* os.path.abspath(rel_path) used instead of cwd + "/" + rel_path
* os.path.join used
* POpen and Reporter used
* System exits rather than returning None when both files and meta-key are used
* os.sep used where "/" was previously used in setting up rel_path
* older %s formatting used for making message to be consistent with usage later on
