Turn shutil into a runnable module

[zhihaoy]

Feature or enhancement

Proposal:

Introduction

py -m shutil copy2 ~/my/src.txt .

I often find it necessary to use some shutil functionalities in scripts. It does the right thing efficiently, has more precise error handling than cmake -E, and, most importantly, is cross-platform.

Precedent

The zipfile module can be used by py -m zipfile. It gains credits for being a cross-platform ZIP64 decompressor.

Details

• The subcommands should cover copyfile, copystat, copy, copy2, copytree, rmtree, move, chown, which, make_archive, and unpack_archive;
• The keyword arguments that are easy to represent in cmdline should be adapted into --kw arg cmdline options; flags can follow the style --follow_symlinks and --no-follow_symlinks.
• It would be even nicer if combined with a progress bar (See also: Add a basic progressbar implementation to shutil)

I'm pretty sure this needs to get discussed on DPO.
