Mark DBT cloud job run failed if cancelled by raising AirflowFailException

[pankajkoti]

Currently, if DBT Cloud job run is cancelled our async operator just logs
a message in the task logs that the job is cancelled and marks the task
status as success.
The PR now raises an AirflowFailException to mark the task as failed
and that it is not retried by Airflow as the user may not pay attention to
re-cancel the job or may not have set retries to 0 for the task in their DAG.

closes: #1081
