> In some cases we need a class which can track the status of the outgoing commands.
> The commands should be resent after a while except a status message is received about
command completion.
> On high level, we need a builder factory, which takes the following parameters:
> * (destination) event type and the payload of the command which should be repeated.
> * the ID of the command/event
> * The event/topic of the completion messages. If an IdentifiableEventPayload is received
on this topic, the specific event is done and don't need to resend it.
