-- Unassigns a registered instance from all layers that are using the
-- instance. 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 Stacks.
--
-- __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 about user
-- permissions, see
