Here is an updated 6.x deprecation patch with CHANGES entries. If there are no
objections, I will merge shortly as these large patches do not age well and can
become hard to apply in case of conflicting changes.

> Index-time boosts are a very expert feature whose behaviour is tight to the
> Similarity impl. Additionally users have often be confused by the poor
> precision due to the fact that we encode values on a single byte. But now we
> have doc values that allow you to encode any values the way you want with as
> much precision as you need so maybe we should deprecate index-time boosts and
> recommend to encode index-time scoring factors into doc values fields instead.
