Tom Proctor bee8cb1041 cmd/{k8s-operator,k8s-proxy}: support new ProxyGroup type kube-apiserver
Adds a new enum value to ProxyGroup's .spec.Type field, kube-apiserver. Deploys
the new k8s-proxy container image and configures it via a new config file
specific to k8s-proxy. The config file is modelled after conffile but makes
some minor changes to versioning to make sure we can maintain backwards
compatible config within a single file so that it's easy to implement reading
that config file directly from a Kubernetes Secret in future.

Required significant updates to the operator's permissions so that it is
allowed to assign the powerful impersonation cluster role that k8s-proxy
requires to operate in authenticating mode.

The proxies deployed for the new ProxyGroup type currently work using their
own DNS name, but do not advertise a shared Tailscale Service, so are not
yet HA. Tailscale Service creation is planned to be added in a separate
reconciler loop.

Updates #13358

Tailscale Kubernetes operator deployment manifests

./cmd/k8s-operator/deploy contain various Tailscale Kubernetes operator deployment manifests.

Helm chart

./cmd/k8s-operator/deploy/chart contains Tailscale operator Helm chart templates. The chart templates are also used to generate the static manifest, so developers must ensure that any changes applied to the chart have been propagated to the static manifest by running go generate tailscale.com/cmd/k8s-operator

Static manifests

./cmd/k8s-operator/deploy/manifests/operator.yaml is a static manifest for the operator generated from the Helm chart templates for the operator.
