    Replace eventlet-based raw socket client with requests

    There's no discernable reason why we need to use a raw
    eventlet-based client TestWSGIServerWithSSL to confirm that a
    wsgi server is listening correctly and returning the expected
    response, especially since using eventlet leads to unreliable
    i/o on the socket unless there is an explicit yield before
    asserting the value of the response.

    So requests is used to query the servers and verify the response.
