Qa calls

Merging qa_calls into Master.
There are some precedents in in org.rb and user.rb, but those are also not working. @ncolgan and I discussed last week that, for those cases anyway, we don't want functionality to diverge based on whether or not a class-level client is being used, and decided to remove those methods rather than fix them. Since the class-level client method doesn't exist, please remove this method.
