Add Role-Based Permissions to Trigger Specific Airflow DAGs

[amarouane-ABDELHAK]

Description
Enhance the current Airflow permission model by adding role-based permissions that allow users to trigger only specific DAGs. This will ensure greater control and security in managing workflows, especially in environments with multiple users and sensitive data. The goal of this task is to introduce a role-based access control (RBAC) mechanism to restrict DAG execution based on user roles.

Acceptance Criteria

• Users with specific roles can trigger only the DAGs they have permission to access.

• Admins can assign and revoke permissions for DAGs via Airflow's UI or CLI.

• Changes are reflected without requiring a restart of the Airflow scheduler.
