describe_ring should include datacenter/topology information
------------------------------------------------------------
Key: CASSANDRA-2882
URL: https://issues.apache.org/jira/browse/CASSANDRA-2882
Project: Cassandra
Issue Type: Improvement
Components: API, Core
Reporter: Mark Guzman
Priority: Minor
describe_ring is great for getting a list of nodes in the cluster, but it
doesn't provide any information about the network topology which prevents it's
use in a multi-dc setup. It would be nice if we added another list to the
TokenRange object containing the DC information.
Optimally I could have ask any Cassandra node for this information and on the
client-side prefer local nodes but be able to fail to remote nodes without
requiring another lookup.
