CFT: Update all Delete actions with mandatory placeholder

Resources like the Project Template/ Delete default SA action has a runtimePolicy: Create. This works well until the resource itself is not deleted/abandoned from the Deployment.

For example if removeDefaultSA property gets set to false and then back to true, the is a resource not found error.

To solve this, I propose to create a placeholder resource and make sure the delete action only runs once, no matter how the inputs are changing.
