I believe this is no longer a valid bug. I've manually tested the import and it passed without any error. Also as pointed out by Masayuki many tempest plugins use this import without any issue [1]. Therefore I'm moving this bug to "Invalid". Feel free to change the status if you think this decision is not correct.

It replaces oslo config object with a proxy object. Calling __getattr__ on this object has a side-effect of parsing the config which makes config object no longer capable of registering new CLI opts.
