Disable logs for particular worker

[ppcololo]

Hello. We have some request if possible: we want to disable worker to send logs to logs queue for some workers. Some of our worker produce huge amount of logs and we don't want to send them to MQ > Coordinator > DB. So we need option to fully disable that. Is any env var to do that?

Relates to https://github.com/runabol/tork/issues/349 bit now we really ned to disable it completelly
