To reproduce, on a testing VyOS:

delete firewall
set firewall group address-group test address 1.2.3.4
commit

I would expect the following ansible task to result in one of those 2 being run:

• delete firewall group address-group test address 1.2.3.4
• delete firewall group address-group test address

(both of those result in the same line remaining in the config: set firewall group address-group test)

- name: clear address group test
   vyos.vyos.vyos_firewall_global:
     config:
       group:
         address_group:
         - name: test
           members: []

Currently, nothing happens.
