Kirill Gusakov updated IGNITE-18287:
------------------------------------
    Description: 
We need to provide the protocol for communication between PrimaryReplica and 
appropriate raft groups. It must support
 * Propagation of RAFT reconfiguration events and errors back to PrimaryReplica 
from the leader of RAFT group
 * Propagation of RAFT leader transfers. It needs to restrart the rebalance 
from the PrimaryReplica, if needed

  was:
We need to provide the high level protocol for communication between 
RebalanceScheduler and appropriate raft groups. It must support
 * Propagation of RAFT reconfiguration events and errors back to 
RebalanceScheduler from the leader of RAFT group (maybe current listeners will 
be enough for this task)
 * Propagation of rebalance progress to RebalanceScheduler on demand
 * Rebalance cancellation


> Prepare a bidirectional protocol for PrimaryReplica/Raft group communcation
