Description

I am running an Jupyter notebook with an --profile option.  This works in 2.8.0 but is broken after https://github.com/apache/beam/pull/6847 as the Python PipelineOptions raises "ambiguous option" error due to argparse behavior of trying to autocomplete options by prefix (this behavior is due to https://bugs.python.org/issue29777 which the Python dev team does not want to fix).
