Michal Rostecki c0045f415b 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.

Fix issue with datastore corruption on cluster-reset (#5515)
* Bump etcd to v3.5.4-k3s1
* Fix issue with datastore corruption on cluster-reset
* Disable unnecessary components during cluster reset

Disable control-plane components and the tunnel setup during
cluster-reset, even when not doing a restore. This reduces the amount of
log clutter during cluster reset/restore, making any errors encountered
more obvious.

Michal Rostecki c707948adf 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:

Euan Kemp c2e846dc16 Allow using flannel wireguard backend in a custom config
Ideally we'd have fully fleshed out support for it (i.e. #5011), but
that's a potentially breaking change and taking a little while to merge.

This is a much simpler change which won't break anything, but will allow
a "Type": "wireguard" reference in the "--flannel-conf" custom config
file to work.

Michal Rostecki 4fed9f4052 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.

Increase agent's apiserver ready timeout (#4454)
Since we now start the server's agent sooner and in the background, we
may need to wait longer than 30 seconds for the apiserver to become
ready on downstream projects such as RKE2.

Since this essentially just serves as an analogue for the server's
apiReady channel, there's little danger in setting it to something
relatively high.
