Module Sync Lock State implementation

Implementation of Lock state for module sync watchdog
Cm Handle state is locked if any exception is found
during sync process
Make changes around READY state method in line with the
new schema set
Add last updated time to composite state
Remove running datastore references as this is being done
at a later time
