Code Refactoring Ncmp* to Lcm* as per new scope

- Refactored code to reflect the LcmEvents scope now.
- Test cases updated and dependencies reviewed.
- You can find few occurences of NcmpEvent for now but that will be
  cleaned up once we implement CPS-1104 which is for LcmEvent schema
- UPCOMING: LcmEvent schema and then the code to publish the events on
  cmHandleStates
- LATER : LcmEvents based on public properties update.

Issue-ID: CPS-1137
Change-Id: I9f395ed733b4028e706205894c36a38412e3452e
