> There are use cases where it's useful to be able to trade off performance and 
> memory when accessing top level DocValues ordinals.
> This issue adds methods to the SlowCompositeReaderWrapper and MultiDocValues 
> that allow an acceptableOverheadRatio to be passed in and applied to the 
> OrdinalMapping.
> If people are ok with this approach I will add tests and performance 
> benchmarks.
