> Currently, nodes with one layer topology are allowed to join in the cluster that with
enabling NodeGroup layer which cause some exception cases. 
> When NodeGroup layer is enabled, the cluster should assumes that at least two layer (Rack/NodeGroup)
is valid topology for each nodes, so should throw exceptions for one layer node in joining.
