> When node joins it's expected that MOVING partitions can only belong to joining node.
> But if somehow counters are desynced other nodes can switch state of owning partitions to MOVING too, causing spurious rebalancing and assertions on mapping to moving primary.
> Possible solution: exclude other nodes partitions from switching state to MOVING on node join.
> This only affects persistent groups.
