'Provider' object has no attribute 'revoke_api'

[Udi Kalifon]

In token/provider.py, the following triggers an exception if revoke_api is not loaded

        if self.revoke_api is not None:
            ....

The fix is to set self.revoke_api to None in the init:

    def __init__(self):
        super(Manager, self).__init__(self.get_token_provider())
        self.revoke_api = None

To recreate this, run the test_auth.py unit test:
nosetests test_auth.py

This doesn't appear to be an issue in master (demonstrated below), but IS reproducible on stable/icehouse. Is this reproducible outside of tests?

OK

This is likely due to the @optional decorator doing something wonky.
