When a `google_compute_disk` is attached to a `google_compute_instance`,
deleting can be tricky. GCP doesn't allow disks that are attached to
instances to be deleted. Normally, this is fine; the instance depends on
the disk, so by the time the disk is deleted, the instance should
already be gone.
However, some reports have cropped up (#8667) that deleting disks is
failing because they're still attached to instances. Though this
shouldn't happen, it appears it can happen under some unknown
conditions.
This PR adds logic that will attempt to detach disks from any instances
they're attached to before deleting the disks, adding another safeguard
that should prevent this behaviour.
* provider/google: Fix server/state diff with disk_autoresize
* provider/google: Default true for disk.auto_resize
For sql_database_instance , to match the new API default.
Also adds diff suppression func for autoresize on 1st gen instances
* fix typos
Fixes: #14535
When in a `restricted` cloud, we should fall back to the old method of
tagging. Before this change we saw the following:
```

aws_instance.foo: Refreshing state... (ID: i-0009f227ae24791b9)
The Terraform execution plan has been generated and is shown below.
Resources are shown in alphabetical order for quick scanning. Green resources
will be created (or destroyed and then created if an existing resource
exists), yellow resources are being changed in-place, and red resources
will be destroyed. Cyan entries are data sources to be read.
Note: You didn't specify an "-out" parameter to save this plan, so when
"apply" is called, Terraform can't guarantee this is what will execute.
~ aws_instance.foo
tags.%: "0" => "1"
tags.foo: "" => "bar"
Plan: 0 to add, 1 to change, 0 to destroy.
```
After this patch, we see the following:
```

No changes. Infrastructure is up-to-date.
This means that Terraform did not detect any differences between your
configuration and real physical resources that exist. As a result, Terraform
doesn't need to do anything.
