Limit logs to *burst* messages every *interval* seconds, except of levels >= *except_level*. *except_level* is a log level name like 'CRITICAL'. If *except_level* is an empty string, all levels are filtered. The filter uses a monotonic clock, the timestamp of log records is not used. Raise an exception if a rate limit filter is already installed.
