* Implement the join to seed nodes process When a new node is started started it sends a message to all seed nodes and then sends join command to the one that answers first. * Configuration of seed-nodes and auto-join * New JoinSeedNodeSpec that verifies the auto join to seed nodes * In tests seed nodes are configured by overriding seedNodes function, since addresses are not known before start * Deputy nodes are the live members of the seed nodes (not sure if that will be the final solution, see ticket 2252 * Updated cluster.rst with latest info about deputy and seed nodes
