The more important thing here is that "cluster" semantic can't be used 
anymore for generic grouping as this stated in the docs but means the node 
"thing" now. The main disadvantage is that it is impossible to group 
several classes inside some cluster even in local (non-distributed) mode. 
I'd prefer more clear definitions where clusters is not related to nodes, 
storage or so - it is just grouping term. It will be good to have the 
command like :

CREATE CLUST clust1 at NODES all NODESELECTION round-robin

Next all needed classes can be tied to appropriately created cluster - it 
is much more clear than the current CPU's, nodes 
and default-distributed-db-config.json complex mess.
