Proxmox VE 6.2 + ACME

This video shows configuring Proxmox VE 6.2 to use Let's Encrypt to sign certificates for the cluster node web interface using the ACME DNS plugin, which creates challenge TXT records in AWS Route 53. There's an extra wrinkle though; the hostname for the certificate is not in a zone that exists in AWS Route 53, so a CNAME must point Let's Encrypt to the right resource when verifying the challenge. To make that work, Proxmox needs a special configuration modification to set the alias for the ACME domain using `pvenode`.
