> Triggers for assignments recalculation:
>  * Changes in baseline
>  * Changes in numbers of replicas
>  * Changes in numbers of table partitions
> For 1 phase of the rebalancing algorithm, we need to support the first 2.
>  
> The algorithm must provide the way to:
>  * Recalculate assignments for all partitions and update appropriate assignments keys in metastore
>  * Start all needed new raft groups
>  * Initiate changePeers process and handle failover scenarios for it
>  * Stop all redundant raft groups, when change peers done
