There were improvements to the existing configuration options, Thanks to @pavel-z1 !
- 'firewalld_service_rules' now supports to configure the same service for different zones
- 'firewalld_zone_interface' has been replaced by 'firewalld_zone_interfaces' which allows a pretty possibility to configure multiple interfaces to a zone. Configurations within 'firewalld_zone_interface' will be ignored, place review your configuration!
