    Allow user to override UseDNS in template
    
    You could perhaps have something that overrides a container network
    like this;
    
    ---
    container_extra_networks:
      dns_address:
        ...
        dhcp_use_dns: false
    
    and would take precedence over lxc_container_enable_resolved
    
    Also documentations says UseDNS takes true/false
