CASSANDRA-5339 Add YAML network topology snitch
In order to support having a Cassandra cluster spanning multiple data
centers, some in Amazon EC2 and some not, I'm submitting a YAML network
topology snitch that allows one to configure 'preferred addresses' such as a
data-center-local address. The new snitch reconnects to the node via the
preferred address using the same reconnection trick present in
Ec2MultiRegionSnitch.
I chose a new YAML format instead of trying to extend
cassandra-topology.properties because it is easier to read and allows for
future extensibility.
