Streamlined user management in the Aiven Platform

The Aiven Platform has introduced centralized organization units, users, and groups for efficient user management. This feature streamlines the process of managing users and their access to projects and services on the platform, making it easier to scale setups and gain visibility into users' permissions across organizations. Organizational units are now generally available, allowing users to refine the hierarchy of projects and services. The new groups feature replaces the old teams concept, providing an efficient way to control user access to organizational units, projects, and services.
