Add optional observed timestamp in the cps data api

- Added optional query parameter in cps data endpoints
- Updated service layer and notification to use observedTimestamp

Note:
- NCMP REST endpoints are not updated as a part of this patch
- NCMP does not sent observed timestamp when using cps data services
