### Description

Add feature to EmrStepSensor to bring back the spark task url & logs after task execution

### Use case/motivation

After starting an EMR step task using EmrAddStepsOperator we generally have an EmrStepSensor to track the status of the step. The job ID is available for the sensor and is being poked at regular interval. 

```

[2022-04-26, 22:09:44 UTC] {emr.py:74} INFO - Job flow currently COMPLETED
[2022-04-26, 22:09:44 UTC] {base.py:251} INFO - Success criteria met. Exiting.
[2022-04-26, 22:09:44 UTC] {taskinstance.py:1288} INFO - Marking task as SUCCESS. dag_id=datapipeline_sample, task_id=calculate_pi_watch_step, execution_date=20220426T220739, start_date=20220426T220743, end_date=20220426T220944
```

After the task is completed the status is displayed. If the user wants to review the logs of the task, it is a multistep process to get hold of the job logs from EMR cluster. 

It will be a great addition to add the log url and possibly relay the logs to Airflow EmrStepSensor post completion of the task. This will be very handy when there are failures of many tasks and will make it a great user experience.
