OAuth for SMTP notifications

[boelaars]

Description

Airflow SMTP notification mechanism to be updated with ability to authenticate using OAuth.

Use case/motivation

Airflow does not currently support OAuth for SMTP. Microsoft is removing BasicAuth as capability from Exchange Online globally this September 2025 (Source: Microsoft announcement). This means Airflow users who are also Exchange Online customers will no longer be able to use Airflow to send email notifications. I imagine there's a lot of those.
