Is-classifier property: Unknown or legacy key specified

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU): Jetson
• DeepStream Version: 5.0
• JetPack Version (valid for Jetson only): 4.4
• TensorRT Version: 7.0
• NVIDIA GPU Driver Version (valid for GPU only)

I got this warning on "Unknown or legacy key specified ‘is-classifier’ for group [property] for my config file. My config file is as follows:

[property]
gpu-id=0

You only need to set the network-type, is-classifier is a legacy config item.
