Small health check improvements by Donnerbart · Pull Request #3021 · operator-framework/java-operator-sdk

We're digging into a reported operator health issue right now, and I noticed the for for typo in the debug log.

I also noticed a RetryAndRescheduleTimerEventSource with status UNKNOWN in the event source health indicators, caused by TimerEventSource not implementing the getStatus() method. If that was intentional (since we don't know if the actual timer tasks have been executed successfully), I can drop that commit again.
