This upstream patch addresses an issue with Cinder that can cause
oslo-config-generator to fail to recognize valid namespaces. It has
been integrated into Newton but not yet backported to Mitaka.

    Remove entry_points from setup.cfg
    
    The keystonemiddleware entry_point and the oslo_concurrency,
    oslo_db_concurrency and oslo_messaging entry_points are not
    owned by Cinder so it is possible that Keystone and Oslo could
    move or rename the list_opts methods causing our sample
    configuration generator to break.
    
    This patch removes the lines that register the entry_points since
    they aren't actually adding anything to the sample list of
    configuration options because the options are being added to the
    sample file elsewhere.
