tests: replace pycodestyle with black
Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.
