Fix setup of production and staging instances so that OC sysadmins can update to latest branches

[rdhyee]

Today, I had to futz around with the production server to update it to ekansa/open-context-py at production. Some issues to resolve are the naming of remote branches on the instances and some file ownership issues. Let me record some things I had to do to remind myself what I will need to fix

   73  git remote add upstream [email protected]:ekansa/open-context-py.git
   74  git fetch upstream
   76  git checkout -b production origin/production
   78  sudo -u www-data git checkout -b production origin/production
   86  sudo chown -R www-data:www-data /var/oc-venv
   95  cd /opt/ocweb
   97  sudo chown www-data:www-data *
   98  cd /var/oc-venv
   99  sudo pkill uwsgi
  100  sudo -u www-data /var/oc-venv/.venv/bin/uwsgi --http :8000 --ini /opt/ocweb/uwsgi_oc.ini
  101  sudo /etc/init.d/nginx restart
  106  tail -f /opt/ocweb/access-ssl.log
