feat(index): full sync operations (#11178)

Closes: FRMW-2892, FRMW-2893

**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
