This PR also switched us to using the beta API in all cases, and that had a side effect which is worth noting, note included here for posterity.
=====
The problem is, we add a GPU, and as per the docs, GKE adds a taint to
the node pool saying "don't schedule here unless you tolerate GPUs",
which is pretty sensible.
Terraform doesn't know about that, because it didn't ask for the taint
to be added. So after apply, on refresh, it sees the state of the world
(1 taint) and the state of the config (0 taints) and wants to set the
world equal to the config. This introduces a diff, which makes the test
fail - tests fail if there's a diff after they run.
Taints are a beta feature, though. :) And since the config doesn't
contain any taints, terraform didn't see any beta features in that node
pool ... so it used to send the request to the v1 API. And since the v1
API didn't return anything about taints (since they're a beta feature),
terraform happily checked the state of the world (0 taints I know about)
vs the config (0 taints), and all was well.
This PR makes every node pool refresh request hit the beta API. So now
terraform finds out about the taints (which were always there) and the
test fails (which it always should have done).
The solution is probably to write a little bit of code which suppresses
the report of the diff of any taint with value 'nvidia.com/gpu', but
only if GPUs are enabled. I think that's something that can be done.
* add util for handling wrapped/raw google api errors
* add 404 error handling to shared iam files
* fix errwrap calls in iam files
* fix import
* remove newlines, clear ID for removed state in iam binding
* Add Set method to TerraformResourceData and ResourceDataMock
* Add Id() and SetId() to ResourceDataMock and TerraformResourceData
* Keep only name when reading region or zone field to handle api that returns self_link
- Fetch Zone attribute any place where it *was* being fetched from the schema by
combination schema / provider-level attribute.
- Allow region to be unspecified if zone is specified.
- Switch one example to using provider-level zone as an example.
- Make provider-level zone optional. (Individual resources will fail if they can't find a zone.)
- Add tests for getZone and getRegion.
* Move AliasIpRange helpers into utils
To reflect the fact they'll be used by multiple resources.
* Pass Config to build helpers, not meta
It's the only thing meta is used for.
* Refactor getNetwork util methods to return early for the happy path.
* Update compute APIs
compute.Instance.MinCpuPlatform is now GA.
* Fix panic in TestComputeInstanceMigrateState
This seemed to be a pre-existing issue, i.e. I could repro it in master.

* Use only the v1 API for resource_compute_instance
Alias IP ranges, Accelerators, and min CPU platform are now GA.
* Move common instance code into utils.go
Methods used by both resource_compute_instance and
resource_compute_instance_template are currently spread between their respective
files, and utils.go.
This commit moves them all into utils.go for the sake of consistency. It may be
worth considering an instance_common.go file or similar.
* Unify compute_instance and compute_instance_template network_interface and service_account code
This has the side effect of enabling Alias IP range support for
compute_instance_templates.
* Add tests for compute instance template Alias IP ranges
* Mark instance template region as computed
We compute it from the subnet its network interfaces are in. Note this
is not new behaviour - I believe it was erroneously missing the computed
flag.
* Support guest accelerators for instance templates
Since most of the code is already there.
* Add a test for using 'address' rather than 'network_ip' for instance templates
* Don't mark assigned_nat_ip as deprecated
* Remove network_interface schema fields that don't make sense for a compute instance template
* Add newline after count in instance template docs
* Don't try to dedupe guest accelerator expansion code
The API calls to Google to create guest accelerators take different values
for instances and instance templates. Instance templates don't have a zone
and can thus *only* be passed a guest accelerator name.
* Use ParseNetworkFieldValue instead of getNetworkLink
* Add support for parsing regional fields, and subnetworks specifically
Currently unused because subnetworks may have a separate project from that
of the instance using them, which complicates looking up the project field.
* Fall back to provider region when parsing regional field values
Also slightly refactors getXFromSchema field helper functions for readability.
* Revert to assigned_nat_ip in compute instance docs
* Add beta scaffolding to compute instance and compute instance template
Note these resources don't currently use beta features - this is futureproofing.
* Fix indentation in comment about instance template alias IP ranges
* Consolidate metadata helper functions in metadata.go
* Move compute instance (and template) related helpers into their own file
* Relax diff on maintenance_policy.daily_maintenance_window.start_time
If the maintenance window has been set outside of Terraform to a time with a
single-digit hour (such as 1:00), and the terraform definition is set to the
same hour but with a leading zero as per validation (i.e. 01:00), do not
consider the time to be changed (as we currently don't support update on this
property).
Fixes#719
* Generalise rfc3339TimeDiffSuppress and add more test cases
