Improve code for vSphere metadata setting

[erkanerol]

Intro:

We have discussed metadata in the OVF file for Flatcar in the slack thread and then I opened a PR to fix the Flatcar case #1337

It is still being discussed since the desired output is not clear. On the other hand, the implementation is also problematic. This issue is about the implementation, not about the values/inputs/outputs.

Current Status:

In the code base, there are two different inputs guest_os_type and vsphere_guest_os_type. guest_os_type refers values like centos8-64 or indows2019Server-64 whereas vsphere_guest_os_type refers windows2019srv_64Guest or otherLinux64Guest .

There are some re-assigments in the codebase as below but it doesn't make sense. These refer different types of values.

# https://github.com/kubernetes-sigs/image-builder/blob/7cb76c78e013db59783b93815caf710c5ad34bef/images/capi/packer/ova/packer-node.json#L155
 "guest_os_type": "{{user `vsphere_guest_os_type`}}",

There is a OVF template in the code and it is filled by image-build-ova.py script. The script uses guest_os_type as input and has a static map for guest_os_type -> vsphere_guest_os_type relationship.

What should be improved:

• The re-assignments are useless and wrong. They should be removed.
• The script should also respect vsphere_guest_os_type if it exists and allow users to override the value. The static, hard-coded map is very limiting.
