Support for scheduling and cancelling configuration update in Azure

With this feature, you can now specify a time slot to schedule a configuration update. To do this, you can use the PowerShell command Schedule-ProvVmUpdate.  Any power cycle other than scheduled time slot will not trigger configuration updates.  You can also cancel the update before the scheduled time using Cancel-ProvVmUpdate. 

You can schedule and cancel configuration update of:

• A single or multiple VMs
• An entire catalog
