[pyup-bot]

This PR updates setuptools from 40.5.0 to 40.6.0.

Changelog

40.6.0

-------

* 1541: Officially deprecated the ``requires`` parameter in ``setup()``.
* 1519: In ``pkg_resources.normalize_path``, additional path normalization is now performed to ensure path values to a directory is always the same, preventing false positives when checking scripts have a consistent prefix to set up on Windows.
* 1545: Changed the warning class of all deprecation warnings; deprecation warning classes are no longer derived from ``DeprecationWarning`` and are thus visible by default.
* 1554: ``build_meta.build_sdist`` now includes ``setup.py`` in source distributions by default.
* 1576: Started monkey-patching ``get_metadata_version`` and ``read_pkg_file`` onto ``distutils.DistributionMetadata`` to retain the correct version on the ``PKG-INFO`` file in the (deprecated) ``upload`` command.
* 1533: Restricted the ``recursive-include setuptools/_vendor`` to contain only .py and .txt files.
* 1395: Changed Pyrex references to Cython in the documentation.
* 1456: Documented that the ``rpmbuild`` packages is required for the ``bdist_rpm`` command.
* 1537: Documented how to use ``setup.cfg`` for ``src/ layouts``
* 1539: Added minimum version column in ``setup.cfg`` metadata table.
* 1552: Fixed a minor typo in the python 2/3 compatibility documentation.
* 1553: Updated installation instructions to point to ``pip install`` instead of ``ez_setup.py``.
* 1560: Updated ``setuptools`` distribution documentation to remove some outdated information.
* 1564: Documented ``setup.cfg`` minimum version for version and project_urls.
* 1572: Added the ``concurrent.futures`` backport ``futures`` to the Python 2.7 test suite requirements.
