Description

At present when the storage policy of a directory or a file is changed, we just simply change the recorded policy. But the change of storage policy also change the consume, and that will cause violation of Quota, and cause the consume recorded in DirectoryWithQuotaFeature out of date. 

We should do the quota check and consume update when setStoragePolicy():

1. Compute the new consume and check quota on ancestors. If quota exceed throwing the QuotaExceedException. Else go to 2.
2. Update the consume to all ancestors with Quota.
