 Review comment:
   @Fokko - To further add to Keliang explanation of separating the operator to kick off the job and sensor to monitor the job is to provide flexibility to users. Based on their use case(s), they may have the requirements to kick of multiple jobs/tasks in parallel and then monitor the completion of all Amazon Sagemaker job(s) downstream. Some these jobs may take hours and we don't want to hold the pipeline to initiate other downstream jobs hampering the users from meeting their required SLA. Since there are many other known and unknown scenarios, we are careful not to club both the initialization and monitoring of the job. 
   
   The design is similar to the Amazon EMR - https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/example_dags/example_emr_job_flow_manual_steps.py
