Sphinx is unable to access some MXNet ONNX module functions

[aaronmarkham]

This causes Sphinx to fail processing the API docs when shorthand references are used. I used a workaround in #12317 to just reference the functions the long way.

This means the reference is:
mxnet.contrib.onnx.onnx2mx.import_model.import_model
When it could be:
mxnet.contrib.onnx.import_model

But the shorthand route doesn't work.

Example:

ubuntu@ip-172-31-66-78:~/incubator-mxnet/docs$ python -c "import mxnet.contrib.onnx.onnx2mx"
ubuntu@ip-172-31-66-78:~/incubator-mxnet/docs$ python -c "import mxnet.contrib.onnx.onnx2mx.import_model"
ubuntu@ip-172-31-66-78:~/incubator-mxnet/docs$ python -c "import mxnet.contrib.onnx.import_model"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named import_model

Hi @marcoabreu - this is more of a Python issue on the engineering side than something that can be fixed from within the website or docs systems. I might even label it a bug.

@sandeep-krishnamurthy Could you please label above as [Python, Build, Bug] and remove [Doc, Website]

@aaronmarkham : What needs to be done here for the docs?
