This adds severity as a logstash field for every oslo formatted log line, and does not add any lines which are at DEBUG level. This means we no longer rely on the level=INFO query paremeter in order to remove DEBUG lines, so we will avoid sending them to logstash regardless of whether os-loganalyze is used.
