[Users] letsencrypt script for zimbra

[Lorenzo Milesi]

Hi.

I just made (another, you may say) script for letsencrypt certificate deployment in Zimbra. 
I've chosen to patch nginx config.
It's also almost fully automatic in detecting hostname and other stuff.

I've tested it on 8.7.2_UBUNTU16 only, and it's also missing the renewal part.

Feedback (and PR) welcome:

ciao.
