// When specifying RollbackStack , you preserve the state of previously provisioned
// resources when an operation fails. You can check the status of the stack through
// the DescribeStacks operation. Rolls back the specified stack to the last known
// stable state from CREATE_FAILED or UPDATE_FAILED stack statuses. This operation
// will delete a stack if it doesn't contain a last known stable state. A last
// known stable state includes any status in a *_COMPLETE . This includes the
// following stack statuses.
//   - CREATE_COMPLETE
//   - UPDATE_COMPLETE
//   - UPDATE_ROLLBACK_COMPLETE
//   - IMPORT_COMPLETE
