Configures the execution profile to use DC-aware load balancing. For each query, all live nodes in a primary ‘local’ DC are tried first, followed by any node from other DCs.

Note: Profile-based load balancing policy is disabled by default; cluster load balancing policy is used when profile does not contain a policy.
