oddities

• Engine allow to create cluster with one node, allow add second node, but broken when we remove newly added node (need investigation and workaround)
• Cluster has ID, and does not allow add any custom labels - we can not store additional info
• Node id will be generated at join, and rejoined node has new ID - so cluster allow address node by name (need check behavior of adding two nodes with same host name to cluster)
