Beta 4.3.1 N&N for OpenShift should state that while the CDK is treated as a server, runtime detection is not possible

This may be obvious to some/most users, but it may confuse other users - it would be better to make it explicit that runtime detection is not possible for runtime detection to detect the raw CDK.

Since it's a raw cdk it is proper to fail to detect - here's no real way to detect cdk vs any other random vagrantfile.
