This PowerShell script will:

• Iterate through all of the Azure subscriptions that you have access to in the currently authenticated tenant (Run Connect-AzAccount first to login)
• Find all of the Application Gateways that you have deployed and have access to in the subscriptions
• Collect and report the SKU information on each of the gateways

Note, if the SkuName contains WAF_V2 or Standard_v2 then the gateway is the newer v2 version of the gateway
