      It is possible for a ReshardingCoordinatorService to retry deletion of state document as part of this retry loop due to a transient error. The retry doesn't check if it had already deleted the state document previously and can fail here. This causes the resharding operation to fail with a fatal error and halt the config server node. We should make the deletion idempotent to avoid this scenario from happening.
