The role is using python scripts, executed using standard command plugin to retrieve information old service host from several files. In interest of maintainability we should replace these cases with a module call. Either using existing ansible plugin, or making our own.

Edit: It appears that the functionality was already implemented in builtins as a lookup. The task will be rescoped to use that instead.

Edit2: Back to the module idea. The lookup turned out to be less workable than expected.
