Nginx SSL reverse proxy config for Home-Assistant

1. Forward :80 and :443 to IP running HA.
2. Don't use the HA built-in SSL directives. They never actually worked for me.
3. Do the letsencrypt dance.
4. Create a SSL dhparams file: openssl dhparam -out /etc/nginx/ssl/dhparams.pem 2048. Watch your raspberry getting hot for an hour.
5. Enable nginx config: ln -s /etc/nginx/sites-available/home-assistant.conf /etc/nginx/sites-enabled/home-assistant.conf
6. systemctl restart nginx
