-- Unassigns a registered instance from all of it\'s layers. The instance
-- remains in the stack as an unassigned instance and can be assigned to
-- another layer, as needed. You cannot use this action with instances that
-- were created with AWS OpsWorks.
--
-- __Required Permissions__: To use this action, an IAM user must have a
-- Manage permissions level for the stack or an attached policy that
-- explicitly grants permissions. For more information on user permissions,
-- see
