> A subclass of ReplicaPlacementPolicyDefault, ReplicaPlacementPolicyNodeGroup
> was developed along with unit tests to support the four-layer hierarchical
> topology.
> The replica placement strategy used in ReplicaPlacementPolicyNodeGroup
> virtualization is almost the same as the original one. The differences are:
> 1. The 3rd replica will be off node group of the 2nd replica
> 2. If there is no local node available, the 1st replica will be placed on a
> node in the local node group.
