optparse is Deprecated in python and suggest to use argparse

[zhuofeng6]

What's the problem this feature will solve?

i debug pip in my project, and i found you project are still using optparse module.

class CustomOptionParser(optparse.OptionParser):
    def insert_option_group(
        self, idx: int, *args: Any, **kwargs: Any
    ) -> optparse.OptionGroup:
        """Insert an OptionGroup at a given position."""
        group = self.add_option_group(*args, **kwargs)

        self.option_groups.pop()
        self.option_groups.insert(idx, group)

        return group

    @property
    def option_list_all(self) -> List[optparse.Option]:
        """Get a list of all options, including those in option groups."""
        res = self.option_list[:]
        for i in self.option_groups:
            res.extend(i.option_list)

        return res

but it is deprecated since version 3.2 in python. Deprecated since version 3.2

Deprecated since version 3.2: The optparse module is deprecated and will not be developed further; development will continue with the argparse module.

I think pip should be update, maybe, it is only my suggestion.

Describe the solution you'd like

Use argparse instead, after all optparse is no longer maintained
