      Description

      Additional option of 'nodetool ring' command is not documented.

      Old variant:

        ring                   - Print information about the token ring
      

      New variant

        ring [keyspace]        - Print information about the token ring for a given keyspace (for all keyspaces if it is not specified)
      

      Patch has been attached.

      Some history (I think it will be useful for someone who will have the same problem):
      I have 4-nodes cluster. One of nodes is located in other DC (DC2). I've met the problem that 'nodetool ring' shows that node in DC2 'Owns 0.00%'. I've found following questions:
      http://www.datastax.com/support-forums/topic/owns-in-nodetool
      http://mail-archives.apache.org/mod_mbox/cassandra-user/201202.mbox/%3C323DBC99-8519-4E86-B69B-6520D53FA5CF@humbaba.net%3E
      and task with fix:
      https://issues.apache.org/jira/browse/CASSANDRA-3412

      So you should use 'nodetool ring keyspace' for getting right information.
