Description

When I attempt to set the vApp properties to blank, nothing happens. The diff always comes as it going to set the blank, but it doesn't actually do it.

Expected Behavior

When I'm setting them to blank I expect for them to be set to blank. This is useful when deploying from template, which already has values set. but I want to reset them on the deployed VM.

It also appears that if the value is set to blank, it gets reset the default value from the OVA, which is not correct behaviour.

Actual Behavior

vApp properties are not set to blank. Value get reset to the default.

Note that its possible to set the value to blank in the vCenter interface.

Steps to Reproduce

1. Create VM from OVA using terraform

2. After VM has been deployed, run terraform apply again. The diff shows that instance-id has not been set blank. Keep in mind that the OVA has a default value for that property.

In vCenter UI:

3. Run terraform apply again, and step (2) will repeat.
