Chopped up nginx.conf, extracted the server block to /conf.d/default.conf

[doedje]

As requested in #98

If you just want to redefine a different server-block you can put .conf files in your conf.d directory like:

# conf.d/redirect.conf
server {
	listen 80 default_server;
	listen [::]:80 default_server;
	return 301 https://$host$request_uri;
}

and

# conf.d/my-https-site.conf
server {
	listen 443 default_server ssl;
	listen [::]:443 default_server ssl;
	...
}

You can now run the image as a new container with:

docker run -v "`pwd`/conf.d:/etc/nginx/conf.d" -p 80:80  -p 443:443 trafex/php-nginx

NOTE: don't forget to add a server-block for the healthcheck:

# conf.d/healthcheck.conf
server {
	listen 8080;
	listen [::]:8080;
	# Allow fpm ping and status from localhost
	location ~ ^/(fpm-status|fpm-ping)$ {
		access_log off;
		allow 127.0.0.1;
		deny all;
		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
		include fastcgi_params;
		fastcgi_pass unix:/run/php-fpm.sock;
	}
}

EDIT: removed 'default_server' from the healthcheck server-block and fixed a typo

Hi @doedje,

Thank you for your contribution! That's indeed exactly what's needed to split the http and server config.
I'll merge this in. Nice work!
