DCAwareRoundRobinPolicyNewQueryPlan Method

Returns the hosts to use for a new query.

The returned plan will always try each known host in the local datacenter first, and then, if none of the local host is reachable, will try up to a configurable number of other host per remote datacenter. The order of the local node in the returned query plan will follow a Round-robin algorithm.
