Description

In REEF-54, we discovered that the DriverIdentifier's required nature makes it impossible to just create a template Java Configuration instance to be used by the .NET client.

Turns out that the DriverIdentifier is only ever used on the client side. Hence, we can make it optional and add code to generate a unique ID for when it isn't present.
