Fixes to support renewal with docker's new networking

Browse Source 
Added new replacement variable for nginx-secure: ___NAMESERVER___. This
is parsed out from the system resolv.conf and used to resolve the
ip's of the containers dynamically
Modified nginx-secure.conf to resolve certbot dynamically
NOTE: if using `docker-compose run certbot ...`, set `--name certbot` so it
can be resolved properly
Added CMD /start.sh back in, guessing it was removed by accident
