Event handlers are defined as `EventCommand` objects in Icinga 2.

if defined. Therefore the `EventCommand` object should define a command line

Common use case scenarios are a failing HTTP check requiring an immediate
restart via event command, or if an application is locked and requires
a restart upon detection.
