    Fix usage of setUpClass method in functional tests

    Class method 'setUpClass' is executed for each test of test suite that
    appeared in new thread. It leads to creation of redundant resources,
    and, hence, waste of resources.

    So, add 'group_regex' option in testr config that will make all tests
    of each class run in one thread.
