Alexander Kukushkin bfbc4860d5 PoC: Patroni on pure RAFT (#375) ...

* new node can join the cluster dynamically and become a part of consensus
 * it is also possible to join only Patroni cluster (without adding the node to the raft), just comment or remove `raft.self_addr` for that
 * when the node joins the cluster it is using values from `raft.partner_addrs` only for initial discovery.
* It is possible to run Patroni and Postgres on two nodes plus one node with `patroni_raft_controller` (without Patroni and Postgres). In such setup one can temporarily lose one node without affecting the primary.
