I've tested the behavior of CPUs and cpu_cores against both vSphere 5.5 and 6.7. In both cases, CPUs gives you virtual cores, not sockets.
For example, I want 6 cores per socket across 2 sockets for 12 total cores. Based on the wording of this doc, I set CPUs to 2 and cpu_cores to 6. The documentation implies that will give me 2 sockets with 6 cores each. The actual behavior is you get 2 cores, and when you crack open the VMs configuration, you see that cores per socket is set to 6 -- which is meaningless.
Setting CPUs to 12 and cpu_cores to 6 gives me what I wanted. So the wording I propose is
```
- `CPUs` (int32) - Number of CPU cores.
```
Before change
```
Usage: packer [--version] [--help] <command> [<args>]
Available commands are:
build build image(s) from template
console creates a console for testing variable interpolation
fix fixes templates from old versions of packer
hcl2_upgrade build image(s) from template
inspect see components of a template
validate check that a template is valid
version Prints the Packer version
```
After change
```
Usage: packer [--version] [--help] <command> [<args>]
Available commands are:
build build image(s) from template

fix fixes templates from old versions of packer
hcl2_upgrade transform a JSON template into a HCL2 configuration
inspect see components of a template
validate check that a template is valid
version Prints the Packer version
```
when it encounters map[string]interface{} or []interface{} types, hcl2_upgrade now takes the 'most complex' entry from those in order to tell wether this is going to be a body `body {}` or an attribute `attribute = {}`. Before that the hcl2_upgrade command could be a bit random there.
A way better ( but may be somewhat hard ) way to do this would be to use the actual plugins structs in order to generate the HCL2.
Refactor step_export and the driver interface to move the ovftool call
into the vmware driver. This refactor allows us to add meaningful tests
to step_export, which I have also added here.
