envionment markers with comments error in pbr

[Brant Knudson]

https://review.openstack.org/#/c/222000/ in keystone is a new requirements update that came after https://review.openstack.org/203336 requirements update.

the keystone change is failing, when I run it locally the output includes:

  Running setup.py install for keystone
    Complete output from command /opt/stack/keystone/.tox/py27/bin/python2.7 -c "import setuptools, tokenize;__file__='/tmp/pip-UCUFAy-build/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-ZKQdft-record/install-record.txt --single-version-externally-managed --compile --install-headers /opt/stack/keystone/.tox/py27/include/site/python2.7/keystone:
    error in setup command: Invalid environment marker: (python_version=='2.7' # MPL)
So it looks like something isn't handling comments in setup.cfg lines, or comments can't be put in setup.cfg lines.

A couple of options:

1) Remove the comment from the global requirements file.
2) Have the requirements update tool strip comments when updating setup.cfg.
3) Maybe it's pbr that needs to handle it?
