Support for gcsfuse symlinks. #1701
Description
When using gcsfuse, we could have symlinks in mounted buckets. When looking at these symlinks, they are stored in GCS as empty files with metadata pointing to the target file symlink. Currently, if I access to this file with the java-storage-nio interface, it is seen as an empty file.
It would be great to support them and when we do a NIO operation to a symlink it does to the target file or return a FileNotFoundException when the target path doesn't exist.
