The returned `FileStatus` status of the path additionally carries details on
Encryption and Erasure Coding information. `getFileStatus(Path p).isEncrypted()`
can be queried to find if the path is Encrypted.
Likewise, `getFileStatus(Path p).isErasureCoded()` will tell if the path is
Erasure Coded or not.
