Allow Module Re-Sync

Allows the Resync of an already synced CmHandle
Currently: Advised -(create schemaset)-> Ready -(manual write)-> Advised -> Locked as schemaset for cmhandle already exists
With this: Advised -(create schemaset)-> Ready -(manual write)-> Advised -(delete schemaset, create schemaset)-> Ready
Included some logging
Renamed ModuleSyncSpec -> ModuleSyncWatchdogSpec to match class
