Move custom configurations management to dedicated tasks list

This allows to use the `tasks_from` parameter of the `import_role` module.
For instance, one could run something like :
```
- name: "Create Traefik fail2ban configuration."
  import_role:
    name: ansible-fail2ban
    tasks_from: copy_custom_configurations
  become: True
  vars:
    fail2ban_filterd_path: "{{ traefik_fail2ban_filterd_path }}"
    fail2ban_actiond_path: "{{ traefik_fail2ban_actiond_path }}"
    fail2ban_jaild_path: "{{ traefik_fail2ban_jaild_path }}"
```
from a Traefik playbook to just add Traefik specific Fail2ban configuration
without reconfiguring everything.
