`iptables` is what the CNI bridge plugin shells out to for outbound NAT; `openssh-client` provides
the `ssh-keygen` that generates core's key pair.
`nftables` provides the `nft` the CNI bridge plugin drives for outbound NAT (the conflist sets
`ipMasqBackend: nftables`, which keeps concurrent container starts off the iptables lock);
`iptables` stays for tooling that still expects it; `openssh-client` provides the `ssh-keygen`
that generates core's key pair.
