    Description

      The optional "internalClient" field in the isMaster request determines whether the internal or external client's minWireVersion and maxWireVersion are appended to the response. The StreamableReplicaSetMontior (and ScanningReplicaSetMonitor) currently sends isMaster requests without the optional "internalClient" field. This leads to incorrect minWireVersion and maxWireVersion in ServerDescription and TopologyDescription::checkWireCompatibilityVersions as the minWireVersion for external client is always 0.
