> * The Raft configuration listener should also read pending assignments from
> meta storage interpreting them as a queue;
> * If there is one element in the queue, the configuration listener works in
> the same way as it does now: it saves the new Raft configuration as the
> stable assignments, and pending assignments entry in meta storage should be
> either removed or replaced with planned assignments if they exist, the
> planned assignments are also transformed in PAQ here;
> * If there is more than one element in PAQ, it means that the first element
> was just applied to the configuration. The listener should remove the first
> element from PAQ and save the new PAQ value to meta storage (through CAS with
> revision check, this logic remains). It also verifies that the target pending
> configuration is able to be achieved from the current one through the given
> PAQ, and if not, it should create the new PAQ. In this point, rebalancing is
> not completed and no more actions on this listener are required now;
