The configuration of ``worker`` can be removed for two reasons: * In Mitaka (and onward), it is two separate parameters: ``public_workers`` and ``admin_workers`` under section [eventlet_server], as shown in [1]. In master (Ocata), these options were removed. * In the preferred keystone deployment of using u/wsgi, and not eventlet server, this setting does not really take effect - as Apache will manage this instead of keystone. These options can be removed. Also, removed extra EOL spaces. [1] https://github.com/openstack/keystone/blob/stable/mitaka/etc/keystone.conf.sample#L678-L696
