Support bringing up a new datacenter to existing cluster without repair
-----------------------------------------------------------------------

                 Key: CASSANDRA-3483
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3483
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.0.2
            Reporter: Chris Goffinet


Was talking to Brandon in irc, and we ran into a case where we want to bring up a new DC to
an existing cluster. He suggested from jbellis the way to do it currently was set strategy
options of dc2:0, then add the nodes. After the nodes are up, change the RF of dc2, and run
repair. 

I'd like to avoid a repair as it runs AES and is a bit more intense than how bootstrap works
currently by just streaming ranges from the SSTables. Would it be possible to improve this
functionality (adding a new DC to existing cluster) than the proposed method? We'd be happy
to do a patch if we got some input on the best way to go about it.
