docs: Return the status of a task or timeout.
  
          There are several API calls that trigger asynchronous tasks, such as
          synchronizing a repository, or publishing or promoting a content view.
          It is possible to check on the status of a task if you know its UUID.
          This method polls a task once every ``poll_rate`` seconds and, upon
          task completion, returns information about that task.
  
          :param poll_rate: Delay between the end of one task check-up and
              the start of the next check-up. Defaults to
              ``nailgun.entity_mixins.TASK_POLL_RATE``.
          :param timeout: Maximum number of seconds to wait until timing out.
              Defaults to ``nailgun.entity_mixins.TASK_TIMEOUT``.
          :returns: Information about the asynchronous task.
          :raises: ``nailgun.entity_mixins.TaskTimedOutError`` if the task
              completes with any result other than "success".
          :raises: ``nailgun.entity_mixins.TaskFailedError`` if the task finishes
              with any result other than "success".
          :raises: ``requests.exceptions.HTTPError`` If the API returns a message
              with an HTTP 4XX or 5XX status code.
