Ross Scroggs 908edff878 Fix error; DASA suggestions (#1236)
* userKey and customer is an invalid combination; userkey and domain is allowed

* DASA suggestions

I would not use OAUTHFILE to distinguish between normal/DASA, it seems to me that this might lead to oauth2service.json getting deleted by accident.

By using enabledasa.txt you can flip between the two modes easily.

* Update __init__.py

Is this what yuou meant?
