> In {{TrashPolicyDefault}}, the {{.Trash}} directory will be created with permission 700 without sticky bits by the first user that attempts to move a file to the trash. This causes issue when a second user tries to move a file to that trash because the second user might not have the permission to the trash.
> Only affects the user when trash is enabled inside snapshottable directories, and when the user doesn't have admin permissions.
> Solution: Create a .Trash directory with 777 permission and sticky bits enabled (similar solution as HDFS-10324).
> Also need to deal with some corner cases:
> 1. even when the snapshottable directory trash root config is not enabled, create the {{.Trash}} directory anyway?
> 2. When immediately disallowing trash, it shouldn't fail. i.e. remove the empty .Trash directory when disallowing snapshot on a dir
