       Sets the hedge document to be used for the read preference. Sharded clusters running MongoDB 4.4 or later
       can  dispatch  read operations in parallel, returning the result from the fastest host and cancelling the
       unfinished operations.

       For example, this is a valid hedge document

          {
             enabled: true
          }

       Appropriate values for the enabled key are true or false.

       • read_prefs: A mongoc_read_prefs_t.

       • hedge: A bson_t.
