remove netaddr dependency

[Bierchermuesli]

I got some pip issues, as it is not recommended anymore since PEP 668. My intend was to replace pip to package (as we deal with general Debian playbook) something like:

hc_packages:
 - 	python3-netaddr

    - name: install controller dependencies 
      ansible.builtin.package:
        name: "{{ hc_packages }}"
        update_cache: yes
        cache_valid_time: 86400
        state: present
      become: True      

However then I noticed netaddr is not in use (anymore?) maybe was it part of the filter plugin?

Anyway: very cool playbook, thank you for sharing!
