Currently in sharded clusters, set-/removeQuerySettings commands build the parameter on the router and send it to the configsvr via setClusterParameter command.

The goal of this ticket is to make set-/removeQuerySettings forward the request from the router to the configsvr, while on the configsvr the new parameter value will be built and the corresponding setClusterParameter implementation will be used.

This way we may control the old and new behavior on the configsvr via the feature flag with FCV.
