Deprecation warnings

[grawlinson]

I'm in the process of packaging this for Arch Linux, there's quite a few deprecation warnings displayed when building this using either legacy setup.py or the build module (PEP-517 compatible).

/usr/lib/python3.10/site-packages/setuptools/dist.py:770: UserWarning: Usage of dash-separated 'description-file' will not be supported in future versions. Please use the underscore name 'description_file' instead

For some reason, some warnings are displayed twice.

• The dash-separated ones are easily fixable:

• The python setup.py build/install one is trivial (we are migrating away from using setup.py because it is legacy).

• The easy_install one seems to be linked to the usage of the pbr module. I suggest that moving away from pbr would be in this project's best interest.

Related warning on debian bookworm:

DEPRECATION: sphinxcontrib-fulltoc is being installed using the legacy 'setup.py
install' method, because it does not have a 'pyproject.toml' and the 'wheel'
package is not installed. pip 23.1 will enforce this behaviour change.
A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559
