7227d06156 [Metrics] [KVConnector] Add Offloading Connector metrics (#27942) 
Added queries and hits metrics for the Offloading Connector.

Also added timing metrics for store and load operations, which take the
average time it takes to load/store, per-token.

The metrics are available from Prometheus and from the StatLogger.
