The config server needs to create new initial split points using the ReshardingSplitPolicy. There are two options:
1. configsvrReshardCollection does this and passes the generated chunks to the resharding coordinator using setInitialChunksAndZones. If we go this route we must avoid generating new initial chunks if we're retrying configsvrReshardCollection and a ReshardingCoordinatorService already exists on disk.
2. The coordinator does this as a part of _init(). This mean we only pass zones with setInitialChunksAndZones, unless we are in a test environment and need to pass the preset chunks.
