[FEATURE_REQUEST] Updates to image classification hyperdrive notebook

[jiata]

Description

Update image classification hyperdrive notebook:

• Change to only upload the relevant data, and replace hard-coded foldername in training code.
• Change output dir from "outputs" to: output_folder = os.path.join(current_directory, 'hyperdrive_outputs')
• Rename DATA to DATA_PATH
• hyperdrive_run.cancel() not hyperdrive_run_config.cancel()

Note: I had updated these points for the object detection hyperdrive notebook, but did not make the changes in the image classification one.
