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:

This controller only needs to run when using managed etcd, so move it in
with the rest of the etcd stuff. This change also modifies the
controller to only watch the Kubernetes service endpoint, instead of
watching all endpoints in the entire cluster.

Fixes an error message revealed by use of a newer grpc client in
Kubernetes 1.24, which logs an error when the Put to etcd failed because
kine doesn't support the etcd Put operation. The controller shouldn't
have been running without etcd in the first place.

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.

This allows secondary etcd nodes to bootstrap the kubelet before an
apiserver joins the cluster. Rancher waits for all the etcd nodes to
come up before adding the control-plane nodes, so this needs to be
handled properly.
