  [sql_cacher] Added "status/report" support

Each full-cache is a status/report (SR) identifier. It's status provides information DB data loading, like -2 (no data) , -1 (initial loading) , 0 (data available), 1 (reloading).
The reports will log when a reload is done and what was the outcome of the reload (success or failure). If success, a more detailed report is generated with how many records were loaded / discarded.
