Description of PR
Optimize the process by reducing some extra QPS.
1 Create: Reduce one HEAD operation for coverage operations.
2 Rename: Reduce an additional PUT operation. During the rename process, when determining whether to create a virtual empty directory, we check if the parent directory exists afterward. There is a bug in the original OSS code that leads to it creating the directory every time.
3 Delete: Reduce one HEAD operation when creating a virtual parent directory. For the operation of creating a parent directory, use OSS server features to create it only when the target does not exist.(([https://www.alibabacloud.com/help/en/oss/user-guide/simple-upload?spm=a2c63.p38356.help-menu-31815.d_2_3_1_0.13644b78AT3Hyj)]
