Update all Python dependencies
Description
When running the test suite I noticed two separate warnings:
- A
UserWarning
for /usr/lib64/python3.x/distutils/dist.py:274. - A
Deprecation
warning for pluginbase.
When looking at the latest pluginbase release, I noticed that this deprecation issue was resolved, so I followed our contributing guidelines which resulted in updating all of our Python dependencies. I don't see any policy concerning when we should update all plugins and AFAICT this has not broken anything. So perhaps now is a good time to update.
Additionally, the two warnings no longer appear.
