Move task handlers to airflow.providers package

[mik-laj]

Hello,

We have the airflow.providers package, which should contain items specific to specific sevices/software. We should move the handlers to this package. I don't have an idea for the specific structure of the package yet, so I'm open to suggestions.

We have the following files left to move.

• airflow/utils/log/wasb_task_handler.py
• airflow/utils/log/cloudwatch_task_handler.py
• airflow/utils/log/gcs_task_handler.py
• airflow/utils/log/es_task_handler.py
• airflow/utils/log/stackdriver_task_handler.py
• airflow/utils/log/s3_task_handler.py

Each move should be moved out in a backward-compatible manner. We should add a note in UPDATING.md also.

Cheers

Hi, can I work on these while I await your reviews on the other PRs? It seems easy, thanks.
