> Path/Permission snapshot read from DB.
> * Refactor full snapshot retriever APIs in SentryStore to become a single
> transaction to ensure snapshot consistency.
> * Added Path/PermissionImageRetriever classes to retrieve
> Path/PermissionImage from DB and convert to corresponding
> Path/PermissionUpdate, which later would be consumed by NN plugin.
