User Layers/UPL policy support for AD attributes

This enhancement enables admins to incorporate Active Directory attribute variables in the policy which defines the network path to where the user layers are located.

Enabling the use of AD attributes (along with environment variables which are already supported), admins can dynamically attach a user layer to a machine based on properties, such as the AD user login, or other AD properties of the user.

This feature is now available in App Layering 2304:
