[PATCH 4/4] docker-compose: Massively simplify

[Stephen Finucane]

Now that we can run tox on the localhost, we no longer need to install
the variety of Python versions we previously did and can keep this
purely for the 'manage.py' use cases.

Note that we're also able to remove the 'libmysqlclient-dev' and
'mysql-client' packages thanks to our switch to 'PyMySQL', which is pure
Python.
