What would you like to happen?

Currently, if we run a pipeline with a large pipeline option in Python on Dataflow, we would see an error Python exited: fork/exec /usr/local/bin/python: argument list too long.

We have solved similar issues in Java and Go(#27839 (comment)), and we should also support this in Python.
