Alistair Coles 348bd83b7e Respect co-builder partition moves when min_part_hours is zero ... Repeated calls to each co-builder's _update_last_part_moves() are unnecessary and have the unfortunate side effect of resetting the _last_part_moved bitmap. When a component builder has zero min_part_hours this results in it not preventing its co-builders from moving parts that it has already moved. This patch changes the CompositeRingBuilder to call each component builder _update_last_part_moves() *once* before rebalancing any component builder. CooperativeRingBuilder's no longer forward calls to their _update_last_part_moves() method. Each component's _last_part_moved bitmap is therefore preserved until for the duration of the composite rebalance. The initialisation of the RingBuilder _last_part_moves array is moved to the RingBuilder __init__ method, so that calls to _update_last_part_moves() are effective even when rebalance() has never been called on that builder. Otherwise, during a composite rebalance, a component that has not previously been rebalanced will not have its _last_part_moves_epoch updated during rebalance and as a result may report erroneous min_part_seconds_left after its first rebalance.
