Support for configuring Hyperdisk provisioned Throughput and IOPS

[FearlessHyena]

TL;DR

Since Hyperdisks allow you to specify the Throughput and IOPS that should be provisioned when creating them, it would be great if the node_pools property added support for them

Terraform Resources

Detailed design

Two new variables under the `node_pools` property would be needed which would only be used in case of Hyperdisks and ignored for Persistent disks. The [google_compute_disk resource] (https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_disk) can be used for reference
- disk_provisioned_iops
- disk_provisioned_throughput

There is also the [enable_confidential_compute](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_disk#enable_confidential_compute-1) property but not sure if it would be in scope of this feature request
