Create new Callback Types

[GuilhermePessoni]

Description

In versions 2.7.3 or lower, in the process of sending callbacks, they are sent in each taskgroup, and not by dag's.
The proposal is to create a new callback flow where sending takes place by each dag and not by each Taskgroup

Use case/motivation

In these cases, Airflow sends 8 callbacks, 1 per taskgroup, the purpose is send only 1 callback alert

TaskGroup it is a UI / Namespace feature, and do not have own states, like a DAG or TaskInstance have, that mean without significant changes in Airflow codebase it is unlikely could be implemented.

I would recommend to start discussion in Dev List first: https://airflow.apache.org/community/
