arg_validator: accept None as valid input for ArgValidatorList

Browse source 
Users might want to use jinja2 templates to set properties. As such,
it's convenient to accept None as an alias for an empty list.

For exmaple, setting like `"match": {"path": None}` will be allowed by
the role:

        network_connections:
          - name: enp0s8
            type: ethernet
            persistent_state: present
            state: up
            match:
              path:
            ip:
              route_metric4: 10
