automation: delete code related to Python 2.7 support

feeding into it.

Tests of revision branch name caching
We rev branch cache is updated automatically. In these tests we use a trick to
trigger rebuilds. We remove the branch head cache and run 'hg head' to cause a
rebuild that also will populate the rev branch cache.
revision branch cache is created when building the branch head cache
$ rm -rf .hg/cache; hg head a -T '{rev}\n'
