[quant][fx] add _remove_qconfig flag to convert_fx (#53166)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/53166
Context: For fx modules that consist of scriptmodules, calling
delattr(module, 'qconfig') throws an attribute error. will follow up
with a separate issue/repro to fix this problem
This PR adds a temporary flag to convert_fx API to preserve the qconfig attributes on the converted model
We will remove this flag once we reach a conclusion on calling delattr on scriptmodules
Test Plan:
python test/test_quantization.py test_preserve_qconfig
