apache-frontend: Jupyter Notebook and evensource support with NGINX

  Introduce NGINX on the same partition of apache to handle websocket\
  and eventsource types.

  The NGINX will run on another port and it would require a second ip at
  the machine for enable it.

  This configuration is a working version with fully https support, but
  some additional adjustments might be required.
