    Reactivate wsgi test related to socket option under python 3
    
    Previously these tests was ignored surely because the WSGI tests
    with SSL were broken due to some design changes introduced by python 3.7 [1]
    in the SSL module of the stdlib.
    
    However, unlike the other WSGI/SSL tests these changes don't use
    the `requests` module or high level modules which are broken by
    the monkey patching of the stdlib.
    
    I suppose previous developers simply turned off all of tests related to
    WSGI/SSL without much more details than "SSL tests with python 3 and eventlet
    is broken" but some of them don't need much more work than just reactivate
    them to be ran successfully.
    
    This test seems to work without change, and it run successfully locally.
    
    Let reactivate this test.

  Debugging by hands shown that service starting and closing OK, but
  when we request something from it using py3 and SSL then we do not get
  answer at all. In case of unit tests we face test timeout.
