CmHandle registration/module sync watchdog performance improvment

- Tuned CPS DB parameters
- Removed deprecated CPS DB parameter
- Modified module sync watch logic
- Added aditional logs
- Removed logic to get FragmentEntities as stream
- Removed detaching of fragment entity as it was causing NCMP to break with an exception "SQLSTATE(08006)"
