Vijay updated CASSANDRA-2491:
-----------------------------

    Attachment: 2491_broadcast_address_v2.patch

1) Rebased
2) Attached patch has modification to IncomingTcpConnection (re factor) in order to support Gossiper.instance.setVersion as versions should be on broadcast IP and socket.getInetAddress will break.
3) Allow brodcastAddress to be set by snitch so we can automate via snitch (property or EC2MultiregionSnitch).

> A new config parameter, broadcast_address
> In a cluster setup where one or more nodes is behind a firewall and has a private ip address, listen_address does not allow the hosts behind the firewalls to be discovered by other nodes.
> Attached is a patch that introduces a new config parameter broadcast_address which allows Cassandra nodes to explicitly specify their external ip address. 
> In addition, this allows listen_address to be set to 0.0.0.0 on the already firewalled node.
> broadcast_address fallsback to listen_address when it is not stated.
