    Pass kwargs to ClientWrapper's call() method

    As the ClientWrapper class had no unittests some were added to test
    the specific part of the code for this change. The FakeClient() and
    associated classes from test_driver.py were moved to a common file to
    make it easier to be imported and used by the new unittests.
