> This jira plans to add storage policy support on directory, i.e., users can set/get storage
policy for not only files but also directories.
> We allow users to set storage policies for nested directories/files. For a specific file/directory,
its storage policy then should be its own storage policy, if it is specified, or the storage
policy specified on its nearest ancestral directory. E.g., for a path /foo/bar/baz, if two
different policies are set on foo and bar (p1 for foo and p2 for bar), the storage policies
for baz, bar, and foo should be p2, p2, and p1, respectively.
