Netavark is the name of Podman's new network stack, implemented in Rust. This card entails the creation of a library for adding and removing firewall rules from the system. It will need to interface with iptables, nftables, and firewalld backends (the former 2 ideally directly through the kernel via Netlink, the latter via dbus API). This does not cover the programming of said firewall rules - just the creation of a backend-agnostic library to create them. Depends on RUN-1340
