Migrate role to role in a collection

[Normo]

It feels like support for conventional roles is becoming more and more limited (especially in the Ansible Galaxy). Collections have been the main distribution format for Ansible content for some time now. They can include playbooks, roles, modules, and plug-ins around specific topics.

With the next major release (v4.0.0) we are planning to migrate the hifis.unattended_upgrades role to an Ansible collection. Step by step we will then add all our Ansible roles to this collection. This simplifies maintenance and updating of all our roles and thus enables the long-term development and more regular releases of this role.

We try to respond to your wishes in order to make the migration process as smooth as possible for the user community. We are happy to get your feedback!
