Log Collector and Log Evaluation (for excessive logs and errors) Under Test

[vlerenc]

What would you like to be added:
We don't really collect and look into pod logs regularly, but should do that actually automatically, so that we do not miss excessive (=useless) logs and errors that under normal circumstances should not appear in logs of a healthy system.

Why is this needed:
We sometimes miss excessive (=useless) logs and errors that have otherwise no side effects that the current tests would catch.
