[BUG] VM watchdog device emulation breaks terraform action

[pkonotopov]

Describe the bug

During the creating VM from template which contain hardware watchdog emulation device we have got an errors.

To Reproduce
Steps to reproduce the behavior:

1. Pick any VM template and add to it the hardware watchdog emulation (see the Proxmox API docs about this - https://pve.proxmox.com/pve-docs/api-viewer/#/nodes/{node}/qemu/{vmid}/config, the last string in this doc):

curl --insecure  \
--cookie "$proxmox_cookie" \
--header "$proxmox_token" \
-X POST $proxmox_url/nodes/$proxmox_host/qemu/$vm_template_id/config \
--data-urlencode watchdog="model=i6300esb,action=reset"

2. Create terraform file, smth like this:

resource "proxmox_virtual_environment_vm" "ubuntu-2004" {
  description = "Managed by Terraform"
  count       = 1

  agent {
    enabled = true
  }

  disk {
    datastore_id = var.disk_type.datastore_name
    file_format  = var.disk_type.file_format
    size         = var.disk_type.size
    interface    = var.disk_type.interface
  }

  clone {
    node_name = var.template_source_vm.vm_host
    vm_id     = var.template_source_vm.vm_id
  }
  cpu {
    cores   = 1
    sockets = 1
  }
  memory {
    dedicated = 1024
  }
  initialization {
    datastore_id = var.disk_type.datastore_name
    ip_config {
      ipv4 {
        address = "dhcp"
      }
    }
    user_account { }
  }
  name = (element(var.instance_tags, count.index))
  network_device {}
  node_name = var.template_source_vm.vm_host

  operating_system {
    type = "l26"
  }
  serial_device {
  }
  template = false
}

3. terraform plan
4. See the error:

Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.

proxmox_virtual_environment_vm.ubuntu-2004[0]: Refreshing state... [id=220]

@pkonotopov I've created a fix in #78 which will be released as v0.4.4. I'm also adding a watchdog argument as a new feature in v0.5.0.

Great, thanks!
