To publish the NcmpEvent when there is a change in the cmHandleState ( state transition )

Scenarios to keep in mind

• We have to introduce a detail field in the NcmpEvent payload which can contain the previous state and other details.
• We have to publish an event on public properties update ( even though we dont have any state change ???? ) 

Potential Solutions

1. Use code triggers
2. Any other solution ?

...

• Create a cmHandleState handler which takes in the cmHandleState transition event
  --  Responsible for identifying the state transition
  --  Based on state transition call the relevant methods to create the NcmpEvent accordingly.
  
  
  
• Identify the trigger points in the code where the actual state transitioning is happening and call the handler from there and provide the type of transition.
