az vm create under PowerShell won't permit empty public-ip-address

Description

Outline the issue here: I first noticed this issue with my full az vm create command, and I progressively simplified it until it was basically just az vm create --resource-group TEST --name TEST-VNAS --public-ip-address "" and it still threw the error: az vm create: error: argument --public-ip-address: expected one argument. That’s when I finally thought maybe this is just an issue with az under PowerShell. So I tried my original full command under a simple Command Prompt window, and it worked fine.

–public-ip-address ‘“”’ worked. thanks.

The main reason is because it is assumed that people using Powershell would be using the Powershell cmdlets for working with Azure rather than Azure CLI 2.0.
