Add docs on Audit Logs

[paolaperaza]

What do you see as an issue?

There is very little documentation related to Audit Logs in Airflow. This includes:

• What are audit logs?
• At what level do they exist? (Task, user)
• Where do they show in the Airflow UI?
• What are the events that you can track? (e.g. There’s a separate event for a task failure (failed)and a user setting a task as failed (action_set_failed)

I'm surely missing other things.

Solving the problem

Either create a new doc or add a section to this doc: https://airflow.apache.org/docs/apache-airflow/stable/administration-and-deployment/security/access-control.html
