Azure - VNet-2-VNet Connectivity Using PowerShell Script

The purpose of this script is to create two Azure Virtual Networks in different Azure regions and then make connectivity between them. PowerShell script will create Virtual Networks, Define Virtual Gateways, Virtual Networks Connections and connectivity between them.
