      Description

      CASSANDRA-930 made read repair "fuzzy optional," but this only helps with ConsistencyLevel.ONE:

      • Quorum reads always send requests to all nodes
      • only the first Quorum's worth of responses get compared

      So what we'd like to do two changes:

      • only send read requests to the closest R live nodes
      • if read repair is enabled, also compare results from the other nodes in the background
