Use http for downloads url for gateway_tests

[will-moore]

Currently, over 60 tests are failing with:

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:877)

See https://latest-ci.openmicroscopy.org/jenkins/job/OMERO-test-integration/247/testReport/

This workaround doesn't fix the underlying issue but should allow us to reduce the noise and get the integration tests green (or identify other failures).

This didn't fix the problem https://merge-ci.openmicroscopy.org/jenkins/job/OMERO-test-integration/lastCompletedBuild/testReport/OmeroPy.test.integration.gatewaytest.test_image/TestImage/testSimpleMarshal/

I've changed the job config to:

• remove system-site-packages
• install https://github.com/ome/zeroc-ice-py-centos7/releases/download/0.2.1/zeroc_ice-3.6.5-cp36-cp36m-linux_x86_64.whl which should link against the newer openssl instead.

  
  if [ ! -e $WORKSPACE/.venv3 ]; then
  virtualenv $WORKSPACE/.venv3 # --system-site-packages
  fi

source $WORKSPACE/.venv3/bin/activate

pip install https://github.com/ome/zeroc-ice-py-manylinux/releases/download/0.1.0/zeroc_ice-3.6.5-cp36-cp36m-manylinux2010_x86_64.whl

pip install https://github.com/ome/zeroc-ice-py-centos7/releases/download/0.2.1/zeroc_ice-3.6.5-cp36-cp36m-linux_x86_64.whl pip install -U pip future setuptools pip install markdown pip install mox3 pytest pytest-xdist pip install tables pip install jinja2 pip install omero-py omero-web # Latest in order to stop server.

--exclude
to see if it passes tomorrow
