[DigitalAdapter] - Check & Simplify Constructor, Callbacks Methods

[piconem]

Evaluate the following improvements in the Digital Adapter class:

• Introduce a ConfigurableDigitalAdapter as already done for the PhysicalAdapter. After this change the default DigitalAdapter will not directly manage the configuration
• Simplify Property, Event, and Relationship callback methods since at the moment also the naming convention is not that clear
• Allow the DigitalAdapter to read the Digital Twin State onDemand
• Check the use and need of the method 'notifyDigitalAdapterBound'
• Check Constructor with the correct flag for State Observability
• Rename method onStateDescriptionChange ?

The current callback 'mess' is the following:

• Digital Adapter Start/Stop:
  • onAdapterStart()
  • onAdapterStop()
• Digital Twin Life Cycle Notifications:
  • onDigitalTwinCreate()
  • onDigitalTwinStart()
  • onDigitalTwinSync(IDigitalTwinState digitalTwinState)
  • onDigitalTwinUnSync(IDigitalTwinState digitalTwinState)
  • onDigitalTwinStop()
  • onDigitalTwinDestroy()
• Digital Twin State Variation
  • onStateChangePropertyCreated(DigitalTwinStateProperty digitalTwinStateProperty)
  • onStateChangePropertyUpdated(DigitalTwinStateProperty digitalTwinStateProperty)
  • onStateChangePropertyDeleted(DigitalTwinStateProperty digitalTwinStateProperty)
  • onStateChangeActionEnabled(DigitalTwinStateAction digitalTwinStateAction)
  • onStateChangeActionUpdated(DigitalTwinStateAction digitalTwinStateAction)
  • onStateChangeActionDisabled(DigitalTwinStateAction digitalTwinStateAction)
  • onStateChangeEventRegistered(DigitalTwinStateEvent digitalTwinStateEvent)
  • onStateChangeEventRegistrationUpdated(DigitalTwinStateEvent digitalTwinStateEvent)
  • onStateChangeEventUnregistered(DigitalTwinStateEvent digitalTwinStateEvent)
  • onStateChangeRelationshipCreated(DigitalTwinStateRelationship digitalTwinStateRelationship)
  • onStateChangeRelationshipInstanceCreated(DigitalTwinStateRelationshipInstance digitalTwinStateRelationshipInstance)
  • onStateChangeRelationshipDeleted(DigitalTwinStateRelationship digitalTwinStateRelationship)
  • onStateChangeRelationshipInstanceDeleted(DigitalTwinStateRelationshipInstance digitalTwinStateRelationshipInstance)
• Property Variation
  • onStatePropertyUpdated(DigitalTwinStateProperty digitalTwinStateProperty)
  • onStatePropertyDeleted(DigitalTwinStateProperty digitalTwinStateProperty)
• Event Notification

+1 I found it strange that the DigitalAdapter was parametrized whereas the Physical adapter was not

This was partially addressed in #16 we should close this issue and open new ones with the stuff that was left out
