Description

Copied from https://github.com/hashicorp/terraform-provider-google/issues/9712

Create a datasource for instance groups to retrieve multiple instance groups with filters, such as AWS ASG

This will allow an easier management of MIGs especially when integrating with Google Load Balancer ( google_compute_backend_service ) while having different MIGs created

New or Affected Resource(s)

• google_compute_instance_groups

Potential Terraform Configuration

data "google_compute_instance_groups" "groups" {
  filter {
    name   = "key"
    values = ["Team"]
  }

  filter {
    name   = "value"
    values = ["Pets"]
  }
}

This is a case of a plural datasource. See https://github.com/hashicorp/terraform-provider-google/issues/8255 for more info and some light guidelines for implementation.
