Update with_classes parameter

I only updated the parameters mentioned by Martin on his request.

There are many other outdated parameters:

• class_id
• classification_confidence
• classification_confidence_operator
• classification_high_confidence
• metadata_name
• metadata_operator
• metadata_value
• mirrored
• order
• order_direction
• page
• page_size
• rotation_angle

I think it would be smarter to use our API schema here, as we have all the required details for the validation.
It would be more consistent too (checking that IDs really are IDs and not strings)
