CI: Add '2-connected' topology generator.
If number of servers (master+replicas) is equal to 4 + SUM(1, n, 2^n*5) for
any n >= 0:
* every server has replication agreement with 2 - 4 other servers.
* at least two agreements must fail in order to disconnect the topology.
Otherwise there can be server(s) with single agreement on the edge of the
topology.
