This is the node in the Proxmox cluster, this previously was
create_vm_proxmox_host however, that can cause issues, therefore a
different variable that is defaulted to create_vm_proxmox_host is a
better approach
Removed the previously added variable and replaced it with
create_vm_proxmox_vm_disks, which feels much nicer to use. However some
more work is required here as the module used by the task "Manage
virtual disk for virtual machine", proxmox_disk, doesn't appear to do
any error detection/handling. As such, a resize can fail in Proxmox but
the task will report a successful change.
This variable allows the user to specify SCSI disks that they would like
to be created. Allows them to specify a size, where the drive should
live and the format of the drive.
