add generic shrink function (#13001) 
Add `ReduceResolution` method to `Histogram` and `FloatHistogram`

This takes the original `mergeToSchema` function and turns it into a more generic `reduceResolution` function, which is the building block for the new methods.

The methods will help with addressing #12864.

beorn7 bf0847073d histogram: Modify getBound to deal properly with infinity 
The bucket receiving math.MaxFloat64 observations now has
math.MaxFloat64 as upper bound, while the bucket after it (the last
possible bucket) has +Inf.

This also adds a test for getBound and moves the getBound code to
generic.go (where it should have been in the first place).
