Implementation of "standby cluster" described in #657. Standby cluster consists of a "standby leader", that replicates from a "remote master" (which is not a part of current patroni cluster and can be anywhere), and cascade replicas, that replicate from the corresponding standby leader. "Standby leader" behaves pretty much like a regular leader, which means that it holds a leader lock in DSC, in case if disappears there will be an election of a new "standby leader". One can define such a cluster using the section "standby_cluster" in patroni config file. This section provides parameters for standby cluster, that will be applied only once during bootstrap and can be changed only through DSC.
