TERRAFORM_PLAN_HAS_DESTROY_CHANGES variable is not being set when there are destroy changes in the plan

[jmyers82]

Describe the bug When using the terraform cli for a plan and adding the -publishPlanResults, followed by a terraform cli show command only populates TERRAFORM_PLAN_HAS_CHANGES variable and not the TERRAFORM_PLAN_HAS_DESTROY_CHANGES variable.

To Reproduce Steps to reproduce the behavior:

1. Setup pipeline as follows:

   
   - task: TerraformCLI@0
   displayName: Terraform Plan
   inputs:
   command: plan
   workingDirectory: ${{ parameters.working_dir }}
   publishPlanResults: terraform.tfplan
   commandOptions: -lock-timeout 5m  -input=false -detailed-exitcode -out terraform.tfplan

• task: TerraformCLI@0 displayName: Terraform Show inputs: command: show

  3. Execute pipeline
  4. See error
  No error, just not getting output variable as expected.  I did get an error when I attempted to echo out the var that didnt existed. 

  TERRAFORM_PLAN_HAS_CHANGES==true TERRAFORM_PLAN_HAS_DESTROY_CHANGES : The term 'TERRAFORM_PLAN_HAS_DESTROY_CHANGES' is not recognized as the name of a cmdlet, function, script file, or operable program.

  
  5. The warnings in the pipeline indicate a destroy change:

Setup a powershell task and did a get-childitem Env: There is no env var for destroy changes?

TEMP C:\Users\VSSADM~1\AppData\Local\Temp
TERRAFORM_LAST_EXITCODE 0
TERRAFORM_PLAN_HAS_CHANGES true
TF_BUILD True

Expected behavior I expected there to be both variables set to true TEMP C:\Users\VSSADM~1\AppData\Local\Temp
TERRAFORM_LAST_EXITCODE 0
TERRAFORM_PLAN_HAS_CHANGES true
TERRAFORM_PLAN_HAS_DESTROY_CHANGES true
TF_BUILD True
