Description

Currently the TestSnapshot only uses a static simple directory structure for testing snapshot functionalities. We need to test snapshot under more complicated directory structures.

Also the current TestSnapshot only compares snapshots before/after three types of modifications: file creation, deletion, and appending. We need to test snapshots for more file modifications, including file permission change, replication factor change, owner/group change, and sub-directory creation/deletion.
