logic module to catch unidentified problems

Created by: andreh12

discussing with @gladky we propose the introduction of a logic module which fires when

• there is no (trigger) rate when rate is expected
• no other logic module identifying know error conditions has fired

This will allow to find such cases in the notification manager archive more easily and help to improve the software to identify not yet caught cases in the future.

More specifically, this new logic module will check whether NoRateWhenExpected has fired but no logic module inheriting from KnownFailure has identified a problem.
