User-Facing Change

K3s's external apiserver listener now declines to add to its certificate any subject names not associated with the kubernetes apiserver service, server nodes, or values of the --tls-san option. This prevents the certificate's SAN list from being filled with unwanted entries.
K3s no longer enables the apiserver's `enable-aggregator-routing` flag when the egress proxy is not being used to route connections to in-cluster endpoints.
Updated the embedded containerd to v1.7.3+k3s1
Updated the embedded runc to v1.1.8
Updated the embedded etcd to v3.5.9+k3s1
User-provided containerd config templates may now use `{{ template "base" . }}` to include the default K3s template content. This makes it easier to maintain user configuration if the only need is to add additional sections to the file.
Bump docker/docker module version to fix issues with cri-dockerd caused by recent releases of golang rejecting invalid host headers sent by the docker client.
Updated kine to v0.10.2
