Feature request - Proxmox integration

Proxmox is becoming vastly more popular, in part due to VMware's new licensing schemes/Broadcom's acquisition.  One of the main things we'd love to see in upcoming versions of Device42 is Proxmox inventory integration, similar to D42's VMware integration feature(s), mainly:
* Automatic VM (& Ideally LXC container) discovery
* Association of said resources with the appropriate physical hypervisor/node
* (Discovery) filters for physical interfaces on the (also physical) Proxmox host itself, as the VMs each start up their own interface, which may clutter the list of discovered interfaces
* Ability to only discover VMs (filter out LXC containers), as containers may be numerous and tie up many licenses
* (Virtual) Hardware facts of each VM would also be super-helpful (amount of RAM/disk/etc)

This may be an easier proposition since D42 already supports libvirt/KVM integration, or if there is a guide/howto on modifying Proxmox to support the existing libvirt/KVM protocols to enable discovery, this would be sufficient.

Thanks,
