[FR]: Add support for Workstation Boost Configurations to `workstation-cluster` module

[davidferguson-telana]

The feature request

v5.22.0 of the Google Terraform Provider added support for the boost_configs field to the host.gce_instance argument on the google_workstations_workstation_config resource (diff as didn't make it into release notes).

Please add support for this to the Workstation cluster Module (workstation-cluster) by exposing this field within the workstation_configs variable to enable configuration of one or more boost configurations that workstations created using this workstation configuration are allowed to use.

Proposed solution

Expose a boost_configs field within the existing workstation_configs variable, respecting the structure of the provider module definition here and apply this configuration to the google_workstations_workstation_config.configs resource.

Example:

module "workstation-cluster" {
  source     = "./fabric/modules/workstation-cluster"
  project_id = var.project_id
  id         = "my-workstation-cluster"
  location   = var.region
  network_config = {
    network    = var.vpc.self_link
    subnetwork = var.subnet.self_link
  }
  workstation_configs = {
    my-workstation-config = {
      gce_instance = {
        machine_type                = "e2-standard-4"
        boot_disk_size_gb           = 35
        disable_public_ip_addresses = true
        boost_configs = [
          {
            id           = "boost-1"
            machine_type = "n1-standard-2"
            accelerators {
              type  = "nvidia-tesla-t4"
              count = "1"
            }
          },
          {
            id           = "boost-1"
            machine_type = "e2-standard-2"
          }
        ]
      }
      workstations = {
        my-workstation = {
          labels = {
            team = "my-team"
          }
        }
      }
    }
  }
}
