ip_configuration requires primary field

[sgettys]

The latest version of azurerm_virtual_machine_scale_set requires primary to be set in ip configurations: Running the current code results in the following error:

Error: module.consul_servers.azurerm_virtual_machine_scale_set.consul_with_load_balancer: "network_profile.0.ip_configuration.0.primary": required field is not set

When the following change is made to consul-cluster main.tf then terraform plan runs correctly:

network_profile {
name = "ConsulNetworkProfile"
primary = true

ip_configuration {
  name = "ConsulIPConfiguration"
  subnet_id = "${var.subnet_id}"
  load_balancer_backend_address_pool_ids = [
    "${azurerm_lb_backend_address_pool.consul_bepool.id}"]
  load_balancer_inbound_nat_rules_ids = ["${element(azurerm_lb_nat_pool.consul_lbnatpool.*.id, count.index)}"]
  **primary = true**
}

}
