Open Stack

Miachael,

I have read the commit to add set_config_files, which could be used for testing 
another config file. I have some questions:

1. Why need set self._args via __call__? Valid self._args throw exceptions in 
register_cli_opt, so limit its usage scenerio.

2. Any openstack test code are using it could be my reference?

3. Is it possible that make set_config_files only set 
self.conf.default_config_files, and then call reload_config_files if needed? So 
it can be followed by normal ops like register_cli_opt.


Thanks!
Edwin
