Support for Passthrough Physical Disk to a VM

[zmingxie]

I followed this guide and attached a physical disk to the OpenMediaVault VM on Proxmox: https://pve.proxmox.com/wiki/Passthrough_Physical_Disk_to_Virtual_Machine_(VM)

After doing that, terraform crashes on refreshing the state:

terraform plan -var-file=./credentials.tfvars

proxmox_lxc.tailscale: Refreshing state... [id=proxmox/lxc/500]
proxmox_vm_qemu.pi_hole: Refreshing state... [id=proxmox/qemu/201]
proxmox_vm_qemu.omv: Refreshing state... [id=proxmox/qemu/202]

Planning failed. Terraform encountered an error while generating this plan.

╷

Error: The terraform-provider-proxmox_v2.9.14 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

Looking at the code and the doc, it seems this provider doesn't support attaching raw disk: https://github.com/Telmate/terraform-provider-proxmox/blob/v2.9.14/proxmox/resource_vm_qemu.go#L1581-L1600

Doc: https://registry.terraform.io/providers/Telmate/proxmox/latest/docs/resources/vm_qemu#disk-block

Has anyone tried this? Any workaround suggestions?

@Telmate, Hello! When will this be fixed\released?
