agent(netpol): Explicitly enable IPv4 when necessary
...
Before this change, kube-router was always assuming that IPv4 is
enabled, which is not the case in IPv6-only clusters. To enable network
policies in IPv6-only, we need to explicitly let kube-router know when
to disable IPv4.

netpol: Add dual-stack support

This change allows to define two cluster CIDRs for compatibility with
Kubernetes dual-stuck, with an assumption that two CIDRs are usually
IPv4 and IPv6.
It does that by levearaging changes in out kube-router fork, with the
following downstream release:

netpol: Use kube-router as a library
...
Before this change, we were copying a part of kube-router code to
pkg/agent/netpol directory with modifications, from which the biggest
one was consumption of k3s node config instead of kube-router config.
However, that approach made it hard to follow new upstream versions.
It's possible to use kube-router as a library, so it seems like a better
way to do that.
Instead of modifying kube-router network policy controller to comsume
k3s configuration, this change just converts k3s node config into
kube-router config. All the functionality of kube-router except netpol
is still disabled.
