When destroying infrastructure with `--target`, print out which
infrastructure will be destroyed instead of saying `Terraform will
delete all your managed infrastructure`.
```
terraform destroy --target aws_instance.test2 --target aws_instance.test1
Do you really want to destroy?
Terraform will delete the following infrastructure:
aws_instance.test2
aws_instance.test1
There is no undo. Only 'yes' will be accepted to confirm
```
Omitting `--target` arguments will use the default input description.
```
$ terraform destroy
Do you really want to destroy?
Terraform will delete all your managed infrastructure.
There is no undo. Only 'yes' will be accepted to confirm.
```
