 Description   
Original Downstream Change Summary

This change disables opportunistic read targeting by default, and adds a new server parameter (called "opportunisticSecondaryTargeting") to enable it.

Description of Linked Ticket

As a result of investigation for SERVER-57230, we have decided to disable opportunistic read targeting (except for hedged reads), similar to what was done in SERVER-54278.

Acceptance criteria: running ConnectionsBuildup workload shows an even distribution of work over the secondary nodes.
