[Feature Request]: Add cleanup mechanism for store in SyncService #2111

Implementation ideas

Implement a cleanup mechanism for the store used by header and data sync service that:

1. Deletes headers from the store once they have been successfully:

   • Retrieved via P2P
   • Processed and verified
   • Stored in the headerCache

2. Deletes data from the store once it has been successfully:

   • Retrieved via P2P
   • Processed and verified
   • Stored in the dataCache
