[docs] unify nginx explainers and add apache httpd (#455)

* docs: unify nginx explainers and add apache httpd

there are two places where nginx + certbot is explained, unify that into
one place.
Add apache httpd, following the same steps, but using mod_md for
LetsEncrypt
add a note about #453 in both guides.
Link to both, and call the section reverse proxy, instead of NGINX

* restore full nginx.conf from docker.md

* add installation_guide/apache-httpd.md to mkdocs

-## (optional) NGINX Config
-The following NGINX config is just an example of what this might look like. In this case we assume that a valid SSL certificate is present. For this you can get a valid certificate from [Let's Encrypt](https://letsencrypt.org "Let's Encrypt Homepage") with the [cerbot](https://certbot.eff.org "Certbot's Homepage").
+## (optional) Reverse Proxy

-server {

-    root /var/www/certbot;

+If you want to run other webservers on port 433 or want to add an additional layer of security you might want to use [nginx](./nginx.md) or [Apache httpd](./apache-httpd.md) as reverse proxy
