vsphere-clone - Customize requires Linux Customization Settings

This issue was originally opened by @FF186 as hashicorp/packer#10041. It was migrated here as a result of the Packer plugin split. The original body of the issue is below.

Hi,

I'm wondering why the customize options for vsphere-clone requires the linux_options: or else it says that customize is empty?
I want the ability to only add network_interface.

WORKS
 "customize": {
          "linux_options": {
            "host_name": "packer-test",
            "domain": "test.internal"
          },
          "network_interface": {
            "ipv4_address": "10.0.0.10",
            "ipv4_netmask": "24"
          }
 }

DOES NOT WORK
 "customize": {
          "network_interface": {
            "ipv4_address": "10.0.0.10",
            "ipv4_netmask": "24"
          }
 }

This doesn't seem to be a general question though, does it? This looks more like a bug. Apart from the fact that packer doesn't say explicitly what the issue is (I've just come across this looking the error up), even adding "linux_options" and "host_name" isn't enough. Then it will (this time explicitly) complain that the domain is not set, as if that's supposed to be compulsory.
