SOLR-8198: Change ReducerStream to use StreamEqualitor instead of
StreamComparator
> Change ReducerStream to use StreamEqualitor instead of StreamComparator

>
> Currently the ReducerStream uses a StreamComparator to determine whether
> tuples are equal. StreamEqualitors are a simplified version of a comparator
> in that they do not require a sort to be provided. Using the function
> getStreamSort we are still able to validate the incoming stream's sort and
> pass that on up to any parent stream which might require it.
> This will simplify the use of the ReducerStream in join scenarios where the
> reducer is used to find like records. Such a scenario exists with Inner/Outer
> JoinStream, ComplementStream, and [Outer]HashJoinStreams.
