Add concept of "daemon" actors

Passerelle has an algorithm to automatically terminate the execution of a flow.
(cfr section "Model start-up and shutdown" in
[PasserelleActorDevelopmentGuide#Model start-up and shutdown] )
This mechanism currently only works reliably with fully connected actor graphs,
i.e. where the only actors that don't have connected inputs, are finite source
actors.
With the recent focus on advanced in-model error handling, the use of
ErrorHandler actors will become mainstream. But ErrorHandlers are typically
unconnected (on their input side), and thus prevent the automated termination
of the models in which they're used.
So the engine must be made aware of the fact that such unconnected actors
should not prevent clean & automated model termination, when all other actors
have finished their work.
This can be based on the concept of "daemon actors", comparable to daemon
threads.

Remark that for the new event-driven director (ET domain), this is not an
issue.
For PN-derived directors (thread-per-actor) it is an issue.

Model termination logic is operational for models incl daemon actors, also with
model executions with actor exceptions.
