As an operator of W[CD]QS, I want to have local access to the logs and I want the configuration files to reflect the reality of the service so that I can properly diagnose potential issues.
Currently, we have a logback configuration in /etc/query_service/logback-wcqs-updater.xml, but that isn't loaded as our startup scripts don't configure -Dlogback.configurationFile=.
- changes to logback configuration files are properly reflected in the streaming updater
- logs are available on disk as expected in /var/log/query_service/
- code is simplified to account for the differentiation between WCQS and WDQS
