VM support for Ultra SSD disks and multiple NICs + West US 3

[ninjarobot]

The changes in this PR are as follows:

• Adds the West US 3 location
• Virtual Machines: Support for multiple network interfaces on a VM
• Virtual Machines: Support for multiple IP configs on a NIC
• Virtual Machines: Support for Ultra SSD disk type for high performance data disks.
• Virtual Machines: Availability zone deployment for VM and public IP.

I have read the contributing guidelines and have completed the following:

• [x] Tested my code end-to-end against a live Azure subscription.
• [x] Updated the documentation in the docs folder for the affected changes.
• [x] Written unit tests against the modified code that I have made.
• [x] Updated the release notes with a new entry for this PR.
• [x] Checked the coding standards outlined in the contributions guide and ensured my code adheres to them.

If I haven't completed any of the tasks above, I include the reasons why here:

Below is a minimal example configuration that includes the new features, which can be used to deploy to Azure:

(*
This creates a virtual network with two subnets, one for application servers and one for database servers. The
application servers and database servers are distributed across two availability zones. The application
servers are connected to both subnets. The database servers use Ultra Disks. All of this deploys to 
West US 3, a sustainable datacenter with multiple AZs.
