Issue

Bump Packaging library to major version 21

Why?
I ran into "No module named 'distutils.util'" while configuring Poetry to pull private packages. My environment is: Poetry 1.1.6 on a debian:buster docker image with python 3.8.10. From my quick research, it seems like distutils is not included in the newer versions of debian. Poetry uses ^20.4 version of the Packaging library, which uses Distutils for tagging. Distutils has been replaced with sysconfig in Packaging version 21.0 ( issue 396).

As distutils is being deprecated with python 3.12 (PEP 632), I think the Packaging library should be bumped to major version 21.

Workaround:
For now, I am installing distutils explicitly on my debian image
apt-get install python3-distutils
