Add letsencript SSL signing to GVL auto config

[AndrewIsaac]

Really a GVL deployment issue
Ben did the following to get SSL certs (RT#24819), need to automate.

• installed letsencrypt (apt install letsencrypt)
• generated a new cert that works for {www.,}genome.edu.au {www.,}gvl.org.au
• updated nginx config to use the newly generated key and cert
• added a renewal script at /usr/local/bin/renew_letsencrypt_cert
• scheduled daily run of renewal script

After talking to Simon, I also added 301 redirects to:

• encrypt all traffic
• send all traffic to the canonical hostname, www.gvl.org.au

Noticed that GVL's are not using https, is this related?

Thanks, this is very useful. There is an option to enable https in cloudman, but that generates a self-signed certificate. As a result, you get warning about it not being trusted on first login. letsencrypt should solve that problem.
