-- For a specified stack that is in the 'UPDATE_ROLLBACK_FAILED' state,
-- continues rolling it back to the 'UPDATE_ROLLBACK_COMPLETE' state.
-- Depending on the cause of the failure, you can manually
-- <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/troubleshooting.html#troubleshooting-errors-update-rollback-failed fix the error>
-- and continue the rollback. By continuing the rollback, you can return
-- your stack to a working state (the 'UPDATE_ROLLBACK_COMPLETE' state),
-- and then try to update the stack again.
--
-- A stack goes into the 'UPDATE_ROLLBACK_FAILED' state when AWS
-- CloudFormation cannot roll back all changes after a failed stack update.
-- For example, you might have a stack that is rolling back to an old
-- database instance that was deleted outside of AWS CloudFormation.
-- Because AWS CloudFormation doesn\'t know the database was deleted, it
-- assumes that the database instance still exists and attempts to roll
-- back to it, causing the update rollback to fail.
