Feature: Zone management

[rmoriz]

As a firewalld user I want to be able to manage zones for complex setups and multiple interfaces

eg two ethernet devices - I want to manage the devices that are in the zone "public" and "internal" and/or create a new custom zone.

[sspans]

yes please!

Just to be clear; this would provide a resource/provider for the following example?

firewall-cmd --permanent --zone=trusted --change-interface=docker0
