paths/notificationRules - GET definition contains query param `checkID` which does not seem to be implemented

[karel-rehor]

While writing tests for the endpoint notificationRules I've tried to filter using the checkID parameter defined in common/paths/notificationRules.yml but it seems to have no affect. Even illegal ID Values (e.g. ?checkID=12345678 should throw an error that ID must have a length of 16 bytes) are passed without issue.

Is this the remains of an idea that was later implemented differently and should be removed, or is this something awaiting implementation?
