Description
Currently, when using consul and ribbon (ZoneAwareLoadBalancer), multiple data centers are not supported so it is not really zone aware.
Looks like a simple change in the getServers method in ConsulServerList to first query for all data centers and after it query each data center for the healthy services.

Research direction
Start with the ConsulServerList class and its getServers method. Trace how the current Consul query selects a data center and how ZoneAwareLoadBalancer consumes the returned services. Done means healthy services are collected across all available data centers so the result supports zone-aware load balancing.
