Settings: rewrite

[saltydk]

Clean up the settings role to use dynamic include_tasks instead of the current implementation that is fairly spammy and confusing to debug.

Current implementation:

- name: "Settings | Migrator"
  ansible.builtin.include_tasks: "subtasks/migrator.yml"
  vars:
    file: "{{ outer_item }}"

Initial suggestion would be:

- name: "Settings | Migrator"
  ansible.builtin.include_tasks: "subtasks/migrator/{{ outer_item }}.yml"

This would avoid looping over tasks that aren't going to do anything over and over.
