simple helper function to override an ONNX graph's input shape to a target shape
added to set a hardcoded starting shape for yolov5 graph exports with dynamic shape. (dynamic shape export is required to change image size, however deepsparse engine requires a static input shape and static input shapes provide good information for model analysis and shape inference)
test_plan:
manual, see yolov5 pr for extensive testing
