    Mock keystone call to avoid test failure

    The test test_password_prompted() was expecting a keystone failure, but
    because of an error in the requests/urllib3 library it was returning a
    different exception and causing our tests to fail, see[1].

    Independent of the the problem above on tests we should not rely on some
    external library failing like that, we should mock this failures to make
    our tests more reliable and that's what this patch is doing.
