**What**
Wired up the building block that we merged previously in order to manage data synchronization. The flow is as follow
- On application start
- Build schema object representation from configuration
- Check configuration changes
- if new entities configured
- Data synchronizer initialize orchestrator and start sync
- for each entity
- acquire lock
- mark existing data as staled
- sync all data by batch
- marked them not staled anymore
- acknowledge each processed batch and renew lock
- update metadata with last synced cursor for entity X
- release lock
- remove all remaining staled data
- if any entities removed from last configuration
- remove the index data and relations
