timeout while waiting for state to become 'created'

[udayas81]

module "nat-zone-1" {
  source     = "../../"
  name       = "${var.network_name}-"
  region     = "${var.region}"
  zone       = "${var.zone1}"
  network    = "${var.network_name}"
  subnetwork = "prod-public-web-us-central1"
}

module "nat-zone-2" {
  source     = "../../"
  name       = "${var.nservice_account_scopesetwork_name}-"
  region     = "${var.region}"
  zone       = "${var.zone2}"
  network    = "${var.network_name}"
  subnetwork = "prod-public-web-us-central1"
}

module "nat-zone-3" {
  source     = "../../"
  name       = "${var.network_name}-"
  region     = "${var.region}"
  zone       = "${var.zone3}"
  network    = "${var.network_name}"
  subnetwork = "prod-public-web-us-central1"
}

Then I run terraform apply I get:

null_resource.dummy_dependency: Refreshing state... (ID: 5457516150144046587)
data.google_compute_instance_group.zonal: Refreshing state...

I think the health check is making the instance group periodically timeout.

Fixed with #79.
