Avoid dumping environment variables in JobNotificationObserver

[Sytten]

While looking at our logs, I realized that we have a lot of:
JobNotificationObserver does not handle X where X is JobQueued, JobStarted or JobFinished.
I am not sure where those come from?
Nonetheless, The problem is that this logger dumps all environment variables of the job, which might contain some sensitive information (like DB passwords since chronos doesnt integrate well with vault or other similar products).
Is there a way to avoid the logger from this class from dumping them?
