   I think this field could become just a local variable.

> Currently, the {{ClusterEntrypoint}} is not very modular in the sense that it 
> cannot be really used for testing purposes (e.g. starting a {{Dispatcher}} 
> with a {{WebMonitorRestEndpoint}}). The problem is that the 
> {{ClusterEntrypoint}} combines too many responsibilities (creating the 
> cluster services, starting the cluster components and deciding on when to 
> terminate the JVM process).
> I suggest to make the structure more compositional, meaning to split up the 
> service generation from the cluster component start up. That way we could 
> also remove code duplication between the different {{ClusterEntrypoint}} 
> implementations.
