Please add support for python 3.10

Feature Request

System information

ONNX version (you are using): 1.10.1

What is the problem that this feature solves?

Please detail the discrepancy with our current functionality. When I ran it with python 3.10 and this code:

    reduce_min_node = onnx.helper.make_node('ReduceMin', [tensor], [tensor + '_ReduceMin'], reduce_min_name, keepdims=keepdims)

I got the following error:

  File "/home/chasun/.local/lib/python3.10/site-packages/onnx/helper.py", line 115, in make_node
    node.attribute.extend(
  File "/home/chasun/.local/lib/python3.10/site-packages/google/protobuf/internal/containers.py", line 413, in extend
    for message in elem_seq:
  File "/home/chasun/.local/lib/python3.10/site-packages/onnx/helper.py", line 116, in <genexpr>
    make_attribute(key, value)
  File "/home/chasun/.local/lib/python3.10/site-packages/onnx/helper.py", line 364, in make_attribute
    is_iterable = isinstance(value, collections.Iterable)

AttributeError: module 'collections' has no attribute 'Iterable'
