[Provider: google-cloud] deleting an attached disk should not be possible

[jeff-knurek]

There seems to be enough issues in the past regarding disks that are attached and not being able to properly manage desired state:
#7792
#12760
#12398

But if I run: gcloud compute disks delete DISKNAME
I get the following error from Google:

The following disks will be deleted:
 - [DISKNAME] in [ZONE]

Do you want to continue (Y/n)?  y

ERROR: (gcloud.compute.disks.delete) Could not fetch resource:
 - The disk resource 'projects/-/zones/-/disks/DISKNAME' is already being used by 'projects/-/zones/-/instances/gke-0c4z....'

However, if I comment out the disk configuration in terraform and run apply,

Terraform will perform the following actions:
- module.-.module.-.google_compute_disk.disk
....
Apply complete! Resources: 0 added, 0 changed, 1 destroyed.

This then leaves everything that was attached to it in a strange state of not being able to connect.

My expected behaviour is to see the same error message that the gcloud command outputs.
