title: httplib2 'disable_ssl_certificate_validation=False' not working - Python3
body: <p>I'm running into a strange issue with httplib2 and python3, I have a little script to connect to my test server, I try to disable SSL verification but it still spits out the following:     </p>
  
  <pre><code>  File "C:\Anaconda3\lib\site-packages\httplib2\__init__.py", line 987, in _conn_reque
      conn.connect()
    File "C:\Anaconda3\lib\http\client.py", line 1231, in connect
      server_hostname=server_hostname)
    File "C:\Anaconda3\lib\ssl.py", line 365, in wrap_socket
      _context=self)
    File "C:\Anaconda3\lib\ssl.py", line 583, in __init__
      self.do_handshake()
    File "C:\Anaconda3\lib\ssl.py", line 810, in do_handshake
      self._sslobj.do_handshake()
    ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed    (_ssl.c:600)
  </code></pre>
  
  <p>The code I'm using to connect:</p>
  
  <pre><code>    import httplib2
      url = 'https://www.MyTestServer.com/Test'
      h = httplib2.Http(".cache", disable_ssl_certificate_validation=True)
      h.add_credentials('username', 'password')
      resp, content = h.request(url, 'GET')
  </code></pre>
