> getTrashRoot() in ViewFileSystem calls getTrashRoot() from underlying filesystem, to return the trash root. Most of the time, we get a trash root in user home dir. This can lead to problems when an application wants to delete a file in a mounted point using moveToTrash() in TrashPolicyDefault, because we can not rename across multiple filesystems/hdfs namenodes. 
>  
> We propose the following extension to getTrashRoot/getTrashRoots in ViewFileSystem: add a flag to return a localized trash root for ViewFileSystem. A localized trash root is a trash root which starts from the root of a mount point (e.g., /mountpointRoot/.Trash/\{user}). 
> * If CONFIG_VIEWFS_MOUNT_POINT_LOCAL_TRASH is not set to true, or
> * when the path p is in a snapshot or an encryption zone, return
> * the default trash root in user home dir.
> *
> * when CONFIG_VIEWFS_MOUNT_POINT_LOCAL_TRASH is set to true,
> * 1) if path p is mounted from the same targetFS as user home dir,
> * return a trash root in user home dir.
> * 2) else, return a trash root in the mounted targetFS
> *
