Reintroduce 'seed' nodes, see #2219

Browse source 
* 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
