compute selflinks return back `wwww.googleapis.com` as the domain,
which was causing a perma-diff. Fixing google.cloud's normalization
fixes that.
Fixing the following tests as well, since creating an instance
now works:
- gcp_compute_instance
- gcp_compute_instance_group
- gcp_compute_instance_group_manager
- gcp_compute_instance_template
- gcp_compute_region_autoscaler
- gcp_compute_region_instance_group_manager
- gcp_compute_target_instance
- gcp_compute_target_pool
- bootstrap code was not correctly instantiating the cloud function.
- compute_instance has a typo from a previous commit.
- re-disabling forwarding rule as it still has the backend_service
fingerprint requirement
The test does not yet pass due to a discovered change, but
some progress was made.
- updating disk image to an existing, non-EOL image.
- updating subnetwork configuration.
