Resolve "Add TLS to the nginx setup"

Closes #34 

This change adds the configuration for TLS to the nginx template. It assumes the certificates are placed where certbot/letsencrypt automatically places them if you request them.

See merge request !3

Add configuration of remote servers (checks out code from gitlab), add certbot, install cert, configure nginx, generate dhparams, set hsts and x-frame headers, enable ocsp, have everything work over perfect tls connections yay!

Many more variable defined in vault.yml and dev/vars.yml / live/vars.yml. Automatic secret generation, tweaks in configuration etc..
