Fix certbot auto-renewal & hands-free cert creation

[hcooper]

Auto-renew of certificates should work now (certbot automatically sets it up in /etc/cron.d/certbot). All it needed was cron running in the reverse_proxy container.

This PR:

• Installs cron (and other basic tools), and runs cron at startup.
• Makes the enable_tls deploy command more hands-free. It'll now automatically request certificates for both $WG_HOSTNAME and www.$WG_HOSTNAME without needing human input.
• Deletes add_cert_cronjob which install a renewal cronjob on the VM, not inside the container (and didn't work because of Crontab for cert renewal does not work #27).

[BenjaminPelletier]

This change breaks my ability to enable TLS on my GCP VM with the error service "ropewiki_reverse_proxy" is not running container #1 upon running enable_tls.sh (complete log below). I've confirmed that the head of master still works using the same procedure.

Also, not all sites will want to enable TLS for both the base and www domain names so we should have some setting, prompt, or other input that allows selection of just one of them. This was previously achieved by simply selecting the appropriate sites in certbot.
