ip_configuration requires primary field

[ned1313]

The latest version of the virtual machine scale set resource requires the primary setting within the ip_configuration. The current main.tf has this:
`
network_profile {
name = "${var.network_profile}"
primary = true

ip_configuration {
  name                                   = "IPConfiguration"
  subnet_id                              = "${var.vnet_subnet_id}"
  load_balancer_backend_address_pool_ids = ["${var.load_balancer_backend_address_pool_ids}"]
}

}
`

And that fails on plan with the error:
Error: module.computegroup.azurerm_virtual_machine_scale_set.vm-linux: "network_profile.0.ip_configuration.0.primary": required field is not set

If I change the following to this:
`
network_profile {
name = "${var.network_profile}"
primary = true

ip_configuration {
  name                                   = "IPConfiguration"
  subnet_id                              = "${var.vnet_subnet_id}"
  primary                                 = true
  load_balancer_backend_address_pool_ids = ["${var.load_balancer_backend_address_pool_ids}"]
}

}
`

The plan runs without error.
