Tests fail with new oslo.utils 1.2.1

[Jamie Lennox]

With the move to oslo namespace packages the mocks we use in the auth_token tests no longer work as the path has changed.

The timeutils provides it's own set_time_override mock and we should use that instead of mocking functions directly.

    Use a test fixture for mocking time

    Use a fixture and the mocking functions provided in oslo.utils.timeutils
    rather than mocking the function directly. This broke when the functions
    moved.
