The ACME support has a large number of plugins for DNS challenges, but there does not seem to be an option to run a custom script, or make a customer HTTP(S) request.

I run my own DNS servers, and already wrote a script which certbot is able to call. Something similar for proxmox would be very useful.
The API is very simple - it's a simple HTTPS GET request with parameters token=xxx for auth, record= to specify the record to update and content= to specify the content of the record. The first two parameters would be statically configured and only the last one would need to be supplied by the ACME script.

Is this possible to do with the current implementation, or easy to add?
