>  This change introduces a new MergePolicy.MergeContext interface
>     that is easy to mock and cuts over all instances of IW to MergeContext.
>     Since IW now implements MergeContext the cut over is straight forward.
>     This reduces the exposed API available in MP dramatically and allows
>     efficient testing without relying on IW to improve the coverage and
>     testability of our MP implementations.
