feat: add interface with batch operators and refactor the utils

[ireneisdoomed]

✨ Context

Addition of Google Batch functions using #678 as reference and refactor of the airflow utils we had in common_airflow to interact with the operators into 3 separate modules:

• operators relating to dataproc tasks
• operators relating to batch tasks
• common utils

For reference on how to use the Batch interactors, use the variant index DAG https://github.com/opentargets/gentropy/blob/dfae8582cce328b5f91ff9edb3cb360814318943/src/airflow/dags/variant_index.py

🛠 What does this PR implement

• Batch functions are added into utils/batch.py
• Dataproc functions are moved into utils/dataproc.py
• check_gcp_folder_exists and read_yaml_config are moved into utils/utils.py
• All the modules that used these functions have been updated accordingly to import only what is needed
