feat: add check to see if we're running the tasks against a Rosetta-backed SubApp server based on inventory group membership. This can later be reused to distinguish between Rosetta and Archivematica SubApp servers.

refactor: move tasks for configuring ZIH maintenance window into separate tasks file and assign useful tags

feat: resolves GitLab issue 2368 (https://git.slub-dresden.de/import-jira-projekte/referat_2.3/-/issues/2368) by making sure that all ClamAV components are uninstalled

chore: remove tasks that were needed to migrate SystemD units to their correct location below /usr/ (and crashed our SubApps in 04/2024)

feat: install passlib library for user creation, because crypt library is deprecated and will be removed from Python 3.13

feat: stop disapp.service for maintenance by using 'Conflicts=' statement, which is much more systemd-like and resolves an issue with write access to the disapp.log when stopping the service
