Successful request

If the request is successful while it has been done by the designated controller, the associated target controller is removed from the servedController list.
If the request is successful while it has been done by the originator, or by the designated controller and there is no more recipient, the point session is ended for all the target responsibilities:
- the "PointSession" data related to this session are removed from the SFPL.
- the associated target controllers are removed from the servedController list.
Then the updated SFPL is published using the FlightDataDistributionSubscriber Service Interface in order to be displayed in the Controller HMIs.
