Adding the boot field supported by Proxmox api and proxmox-api-go library.
This is due to a change in Proxmox to allow for multiple boot harddrives which would break the packer proxmox builder (the hardcoded cdn boot value).
Can be specified like the following example:
"disks": [
{
"type": "scsi",
"disk_size": "20G",
"storage_pool": "vmstorage",
"storage_pool_type": "lvm"
}
],
"boot": "order=scsi0;ide2",
"iso_file": "media:iso/{{ user `ubuntu_iso_file` }}"
Not sure this is ideal, but it's a workaround for the #10252 issue.
