add support to vmware_guest for template => vm conversion (#31607)

Browse source 
* add support to vmware_guest for template => vm conversion

While the vmware_guest currently supports conversion of VMs to templates
using the is_template argument, it does not support the inverse:
converting templates back into VMs.  This change adds that
functionality.

When converting a template back into a VM, the extra config option
"uuid.action" is also set so that VMware will automatically create a new
UUID for the converted VM.  If the "uuid.action" setting is already
configured, it will not be modified.  Setting this prevents an
interactive question from being raised when attempting to boot the VM.

* Add integration tests for vmware_guest is_template

* Add additional idempotency test for vmware_guest is_template
