issue2551137, 2551138 - roundup-server SSL issues. Python3 no longer supports socket._fileobject, so fake it using SocketIO and layering io.BufferedReader as in: https://bugs.launchpad.net/python-glanceclient/+bug/1812525 Also handle SSL.ZeroReturnError exception by ignoring it. This exception is thrown when the SSL layer has been closed and a read happens. There is a warning in openssl as well as python docs that the underlying (unencrypted) socket may not be closed. In manual testing, netstat -anp didn't show any unclosed socket so.... Could it leak a fd still, unknown. This also seesm to have fixed an error when running under python2 where socket shutdown throws an error. Maybe ignoring ZeroErrorREturn handled that case? Also added doc to man page recommending not using -s and using a real web server instead. Also added doc on format of pem file passed to -e. No automated testing on this, so no test updates 8-(.
