Domain Join

[201-vm-domain-join-existing](https://github.com/Azure/azure-quickstart-templates/tree/master/201-vm-domain-join-existing)

### Issue Details
Basically I am trying to create a VM in a vnet connected back to on-prem (with vnet peering etc) which all works I can RDP to the machine with no issues. I would like to somehow use the template above to take my newly created VM and add it to my local/on-prem domain controller.

I can add the VM manually to the domain after the VM is built but I would like to automate this if possible:

Main Template:

# Build the Resource Group
resource "azurerm_resource_group" "rsg" {
name = "${var.rsg}"
location = "${var.location}"
}

# Build the Virtual Network
resource "azurerm_virtual_network" "vnet" {
name = "${var.rsg}-vnet"
address_space = ["${var.add-space}"]
location = "${var.location}"
resource_group_name = "${azurerm_resource_group.rsg.name}"
}

# Build subnet
resource "azurerm_subnet" "subnet1" {
name = "Publishing"
resource_group_name = "${azurerm_resource_group.rsg.name}"
virtual_network_name = "${azurerm_virtual_network.vnet.name}"
address_prefix = "${var.add-subnet1}"
}

# Network Security Group
resource "azurerm_network_security_group" "nsg" {
name = "${var.rsg}-nsg"
location = "${var.location}"
resource_group_name = "${azurerm_resource_group.rsg.name}"

}

}

Start with the 201-vm-domain-join-existing template and the azurerm_virtual_machine_extension using JsonADDomainExtension. Review the reported VMAgentStatusCommunicationError and the VM agent or outbound connectivity requirements; done means the extension completes successfully and the newly created VM joins the on-premises domain automatically.
