Review comment:
       PTAL: https://github.com/apache/airflow/pull/8550/commits/144b63f4ec9835d8c6c57816ab04761b83bee6c2
   
   Since the `cancel` method is executed only by the operator (`on_kill`) I didn't allow user to configure this timeout because I don't think it is worth to add complexity to the user and the code itself. It is added to prevent hanging this `_wait_for_states` forever when `execution_timeout` is not set and provide more meaningful log message if the timeout eventually occur.
   
   I proposed 5 minutes of default timeout.  @aaltay @kamilwu what do you think about this value ?
