Enable/Disable Data Sync for Cm Handle

-Create API Which will enable/disable data sync enabled flag
-Default functionality of module sync watchdog is to set to false
-Remove global config param
-Will set initial sync state based on data sync enabled flag
-Throws an Exception if the same data sync enabled flag tries
to be set
-Throws Exception if state is not in READY
-Data Sync enabled must be true to complete data sync process
- Delete all resource data within fragment table related
to synced cm handle when data sync is set to false
