Open Stack

Tox 2.0 just came out, and it isolates environment variables - which
is good, except if you use them (which we do). So everything is
broken.

Should fix it until projects have had time to fix up their local
tox.ini's to let through the needed variables.

As an aside it might be nice to get this specifier from
global-requirements, so that its managed in the same place as all our
other specifiers.
