Comment 15 for bug 1721580

The following part of "rabbit_utils.py" seems to be causing the issues:

                if not relation_get(attribute='clustered',
                                    rid=relation_id,
                                    unit=remote_unit):
                    log("{} is not yet clustered".format(remote_unit),
                        DEBUG)
                    return False

Again, for some reason the log message is not being logged.
