> Currently, logical topology (which is a set of consistent IDs of the nodes
> that joined the cluster) is stored like this: if we have N nodes in the
> logical topology, we store N entries, one per node.
> IGNITE-18085 requires us to handle logical topology as a whole, also we need
> to store the logical topology version (incrementing it on each change). So we
> should store a BLOB representing the node names and topology version under a
> single key.
