:param node_count: total number of nodes in the replica graph
The intention is that there should be no more than 3 hops
between any two DSAs at a site. With up to 7 nodes the 2 edges
of the ring are enough; any configuration of extra edges with
8 nodes will be enough. It is less clear that the 3 hop
guarantee holds at e.g. 15 nodes in degenerate cases, but
those are quite unlikely given the extra edges are randomly
arranged.
