Rationale

The metrics about the fetched data from the object storage helps estimate the load of query on one specific table, and the table's load distribution can help build a cluster topology with better load balance.

Detailed Changes

Collect metrics for bytes fetched from object storage.

Test Plan

Check the added metrics manually.
