[issue37564] ArgumentParser should support bool type according to truth values

[Zach Beniash]

New submission from Zach Beniash <zbeniash at gmail.com>:

Today when using argparse.ArgumentParser it seems that the bool type is not supported in a logical way.
Foe example:
-------------------------------------
import argparse
parser = argparse.ArgumentParser()
parser.add_argument("--mybool", type=bool)
parsed_args = parser.parse(["--mybool", "False"])
--------------------------------------
parsed_args.my_bool evaluates to True

Instead we should expect to evaluate False here.
