    Add a [placement] section into Neutron config
    
    It appears to be that the Neutron Segment plugin needs to instantiate a
    placement service client which requires credentials and other connection
    details:
    https://opendev.org/openstack/neutron/src/branch/stable/ussuri/neutron/services/segments/plugin.py#L188
    
    Otherwise, the following exception can be seen periodically in the
    Neutron log:
    
    keystoneauth1.exceptions.auth_plugins.MissingAuthPlugin:
     An auth plugin is required to determine endpoint URL
