> RangeSlice requests always do a scheduled read repair when coordinators try to resolve replicas' responses no matter read_repair_chance is set or not.
> Because of this, in low writes and high reads clusters, there are very high write requests going on between nodes.  
> We should have an option to turn this off and this can be different than the read_repair_chance.
