Insights - MySQL query response size metrics
We've added 3 new columns in the data section of the Insights queries table to help track the response size of MySQL queries.

- Bytes returned - The cumulative number of bytes returned to clients
- Bytes returned per query - The average number of bytes returned per query execution
- Max bytes returned per query - The maximum number of bytes returned by any single query execution
These columns are helpful for debugging issues related to unusually large response sizes and identifying the most significant contributors to network egress traffic.
