setup.py is not PEP517 compliant

[Brett Holman]

A bug[1] was filed downstream for this, and reported upstream in #cloud-init IRC by Sam (Gentoo maintainer).

This causes build failure on Gentoo/OpenRC, which is carrying a downstream workaround[2] for now.

It looks like the upstream installation method for init scripts and additional bits (non-Python files at all) isn't compatible with PEP517, so PEP517 installs are broken right now.

PEP517 with the wheel spec doesn't have a good way of installing data files.

From Sam, after sharing the logs:

There's a hint of it at the very end because you see the chmod fails (there was a missing die in the ebuild).

run:

python -m build -C--init-system=openrc # no, that's not a typo, no space after 'C'
python3 -m installer dist/cloud*.whl --destdir=/tmp/foo

/tmp/foo/* only contains the usr/bin and usr/lib/*
