.Introducing flexibility for package installation in `ad_integration` role Previously, the `ad_integration` role always attempted to install the required packages, for example, `realmd`, `sssd-ad`, `adcli`, and many more that are listed in ` __ad_integration_packages`. In environments where external systems handled package management, for example, via configuration management outside of this role, pre-baked images, or immutable systems, this step was redundant and undesirable. With this update, users can now manage package installations through other means and only want this role to join a domain, offering them flexibility. The notable enhancements are: * New Variable: Introduced a new boolean variable `ad_integration_manage_packages` to control whether the role installs packages. * Default Value: The default value is set to `true` in `defaults/main.yml` to ensure backward compatibility. Existing playbooks using this role will continue to function as before without modification. * Conditional Task: Added a `when: ad_integration_manage_packages | bool` condition to the "Ensure required packages are installed" task in `tasks/main.yml`. The task will now only run if the flag is `true` (the default). * Documentation: Updated `README.md` to include the new `ad_integration_manage_packages` variable, explaining its purpose and default value.
