Adjusted VAS view model to better fit Web Service.
Removed some irrelevant fields in PowerSocket, that info is not needed in the VAS service. The information will be stored on a VAS relevant level by filtering the information from the events.
A list of EVSE's is still stored so we can gracefully handle double statusNotifaction events.
Removed 'ipAddress' from charging station model as it's not used. The VAS expects address as the street address.
