At the moment, wdqs logging is managed by logback and is basically:
- send all logs to console, to be managed by journald and sent to file
- send all logs to logstash
What we should have:
- immediately actionable logs should be sent to console / journald (loglevel >= WARN or ERROR)
- logback should log directly to files at level => INFO for wdqs and WARN for others
- logback should log directly to logstash at level => INFO for wdqs and WARN for others
- wdqs-updater needs to be run manually in some cases, those logs should be identifiable (different log files / application name suffix)
