    Add workaround to handle the testtool skip exception in CLI test

    This commit apply the workaround for testtool skip exception
    in CLI test base class.
    - https://review.opendev.org/#/c/681340/6

    I have modified the workaround done in above commit to more generic
    one.

    We are good on skipException from test code. That is handled by
    teststools.TestCase's self.exception_handlers
    - https://github.com/testing-cabal/testtools/blob/f51ce5f934153e80d3e8a95b52e1464daeb30c14/testtools/testcase.py#L275
    Mapped handler _report_skip() will add the respective tests to skip list

    Current CLI test failure

    I have tested both test.BaseTestCase and lib.base.BaseTestCase with all 8 combinations
    of below:
     - py >= 3.5 and py < 3.5 (on py2.7)
     - stestr >= 2.50 and stestr < 2.5.0
     - skip exception from setUpClass and skip exception from test code
