Publish LCM Events

- Publish LCM Create Event when watchdog process moves the cmHandle state from
  ADVISED to READY
- Publish LCM Update Event when public properties are updated, no event
  when DMI propertis are updated
- Publish LCM Delete Event when a cmHandle is been removed
- Related test scenarios update
- See User Story CPS-1034 for related sub-tasks
