GCE support seems stable now, and we have good clarity at the API
level and how that translates to GCP resources, which was our blocker
previously.
Drop the need for the feature-flag.
* Add ILBs, broadly following the AWS model. The following new
capabilities are added for clusters in GCP:
* Cluster's spec.api.loadBalancer can be set to 'type: internal' on
GCP.
* Therefore, GCP can now create:
* regional backend services
* regional (non-legacy) healthchecks
* firewall rules with "internal" load-balancing scheme
* firewall rules with dot-notation-specified IP addresses
* Cluster's spec.api.loadBalancer's 'subnets' field functions
as in the AWS model.
A few incidental changes are included, either because this change
touched the relevant code or because my use case happened to trigger the
issues that are fixed here.
* Cluster's spec.networkID field can be prefixed by project to use
GCP's common cross-project networking model.
* The presumption is that all specified subnets belong to this
network and therefore this project.
* Add missing operation wait on forwarding rule creation.
* Some Terraform output improvements:
* Permit no-ACL files in GCS buckets in Terraform output.
* Enable marginally better cross-resource reference in Terraform outputs
* Add project to network + subnetwork literals in Terraform output.
* Add terraform output to backend services and health checks.
Testing:
* Add mocks for backend services and health checks.
* Add minimal integration test - copied from gce_private and ilb added.
* Add update cluster goldens.

Adding support for the kopeio-networking addon.
We load the operator manifest (which changes rarely) from the channels
directory for now. We follow the same structure as operators
themselves use so that we can support other backends in future.
The channels file includes the current versions of the operators.
During cluster creation, we create these additional objects.
