Dropping Python 2 support
Python 2.7 has been obsolete for more that a year now.
Quoting the announcement for hg-git 0.10.0:
The 0.10.x series will be the last one supporting Python 2.7 and Python 3.5. Future feature releases will only support Python 3.6 and later and Mercurial 5.2 or later.
We now have a separate branch for the 0.10.x series, so we can proceed.
- supported hg versions metadata
- removal of Python 2 CI jobs
- direct dependency onto dulwich 0.20
