For example, "\[AIRFLOW-XXX\] My Airflow PR" - https://issues.apache.org/jira/browse/AIRFLOW-5691 ### Description - [ ] Here are some details about my PR, including screenshots of any UI changes: This PR introduces refactored Dataproc operators that use python client for Dataproc instead of discovery API. Job operators like `DataProcHadoopOperator` are going to be deprecated and user should use generic `DataprocSubmitJobOperator`. In general new operators will accept only request objects like `Cluster` or `Job`. I've added helper methods that will help users to generate those objects using their old operators. This PR also decouples hook, operators any additional Dataproc helpers. ### Tests - [ ] My PR adds the following unit tests __OR__ does not need testing for this extremely good reason: ### Commits - [ ] My commits all reference Jira issues in their subject lines, and I have squashed multiple commits if they address the same issue.
