Enhance Node Bootstrapping, while adding more than 1 nodes to the cluster
-------------------------------------------------------------------------

                 Key: CASSANDRA-2300
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2300
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
    Affects Versions: 0.8
         Environment: JVM
            Reporter: Vijay
            Priority: Minor


Problem: When we add more than one node to the cluster, more than one nodes 
tends to get the same token range and hence we might want to wait till the node 
starts to stream the data (Stage 3)

There are 3 stages while the node trys to bootstrap
1) It understands the Ring
2) It finds a token in the ring and announce to the cluster
3) Start to stream the data.

Possible Solution: If we can move the stage 2 from the bootstrapping node to 
the seed node's, when it starts the boot strapping it will be easier for the 
other nodes who are joining. 

This will reduce the time which is needed for us to add nodes to the clusters. 
This will also reduce the manual work of assigning the tokens when doubling the 
cluster and opens up possibilities of future enhancements to the token 
assignment.
