Require a minimum version of setuptools (#322)
I was using `pex` on an application that lists `google-auth` as a dependency and got the following warning:
..../pex/environment.py:330 UserWarning: The `pkg_resources` package was loaded from a pex vendored version when declaring namespace packages defined by google-auth 1.6.2. The google-auth 1.6.2 distribution should fix its `install_requires` to include `setuptools`
So adding `setuptools` as a listed dependency to fix this.
Version `40.3.0` was chosen because it fixed a bug in the handling of
`pkg_resource`-style namespaces
(https://github.com/pypa/setuptools/issues/1321). For more details on
why this version was picked, see the discussion in
https://github.com/googleapis/google-auth-library-python/pull/322.
