Review comment:
Python 2 is 'gone' more and more distribution removes it as being
'default". You should only run Airflow in Python3 (virtual) environment where
python is python 3. Actually if your default python is python 2, airflow will
likely not work well.
You can even install `python-is-python3` package in older versions of
distributions

We should promote using python2 removal once and for all rather than try to
workaround it and using `python' as python3 equivalent is a very good way to do
it. Let's keep it the way it is.
