Support for using VM’s temporary disk to host the write-back cache disk in Azure environments.

We added an option, Use non-persistent write-back cache disk, to the Machine Catalog Setup > Disk Settings page of the Manage > Full Configuration interface. Select that option if you do not want the write-back cache disk to persist for the provisioned VMs. With the option selected, we use the VM’s temporary disk to host the write-back cache disk if the temporary disk has sufficient space. Doing that reduces your costs. For more information, see Microsoft Azure Resource Manager cloud environments.
