The NetworkTopology can now store costs between a pair of racks. The DatanodeManager invokes the rack awareness script with the "--cost" switch, when a new datanode is registered. This allows it to store the costs between each pair of racks. This basic cost matrix can be used later to make GDA aware decisions
This allows us to configure any link particular link cost script. The earlier approach was to reuse the rack awareness script. This is much cleaner.
