BOOKKEEPER-612: Region aware placement
- Introduce the concept of a two level Network Topology with region as the
first level and rack as the second level
- NodeBase, Node and NetworkTopology manage this two level hierarchy and
position of individual nodes in this hierarchy
- An implementation of RegionawareEnsemblePlacementPolicy that distributes
nodes across regions and within regions uses rack aware placement to place nodes
