Add a script for install "ZeroSSL" certificate in Proxmox Backup Server (PBS)

[IgorIsaiasBanlian]

Let's Encrypt does not allow certifying IPs, only domains. I use my PBS only with an IP, without a domain. ZeroSSL allows certifying IPs, so I would like a script that would allow me to automatically install and configure a ZeroSSL certificate for my public IP accessing my PBS.

Sorry for my bad English.

ZeroSSL supports issuing certificates for IP addresses
