    Description

      I'd like to enhance nodetool ring to show the % of the token range that it is responsible for according to the partitioner (that is, before considering replication). For RandomParitioner this is easy. For OPP we can estimate using describe_splits. I'd also like to issue a warning if any node N has more than 25% more of the ring than another node M.

      (The reason we need to use the range for this instead of load, is load may include an arbitrary amount of data that no longer belongs to the node, pending removal by cleanup.)
