project-config/tools/check_gerrit_projects_changed.py
Clark Boylan 180cc6aeda Be more explicit about using python3 to run tools/
We have python scripts in the tools/ dir the vast majority of which we
run regularly with python3 via our python3 default basepython in tox.
However, most of these use a `python` shebang line which can be
confusing as to whether or not these scripts run under python3 or not.

To make this more clear set them to python3. I've confirmed the scripts
running under tox are happy with these changes. For the ones that don't
run under tox I've done a quick review and they look happy too.
