Containerboot container created for operator's ingress and egress proxies
are now always configured by passing a configfile to tailscaled
(tailscaled --config <configfile-path>.
It does not run 'tailscale set' or 'tailscale up'.
Upgrading existing setups to this version as well as
downgrading existing setups at this version works.

* cmd/k8s-operator,k8s-operator: introduce proxy configuration mechanism via ProxyClass custom resource.
ProxyClass custom resource can be used to specify customizations
for the proxy resources created by the operator.
Add a reconciler that validates ProxyClass resources
and sets a Ready condition to True or False with a corresponding reason and message.
This is required because some fields (labels and annotations)
require complex validations that cannot be performed at custom resource apply time.
Reconcilers that use the ProxyClass to configure proxy resources are expected to
verify that the ProxyClass is Ready and not proceed with resource creation
if configuration from a ProxyClass that is not yet Ready is required.
If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet.
If a tailscale Ingress has a tailscale.com/proxy-class annotation
and the referenced ProxyClass custom resource is available and Ready,
apply configuration from the ProxyClass to the proxy resources
that will be created for the Ingress.
Add a new .proxyClass field to the Connector spec.
If connector.spec.proxyClass is set to a ProxyClass that is available and Ready,
apply configuration from the ProxyClass to the proxy resources created for the Connector.
Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml. Regenerate operator.yaml

* cmd/containerboot,cmd/k8s-operator/deploy/manifests: optionally forward cluster traffic via ingress proxy.
If a tailscale Ingress has tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation, configure the associated ingress proxy to have its tailscale serve proxy to listen on Pod's IP address. This ensures that cluster traffic too can be forwarded via this proxy to the ingress backend(s).
In containerboot, if EXPERIMENTAL_PROXY_CLUSTER_TRAFFIC_VIA_INGRESS is set to true
and the node is Kubernetes operator ingress proxy configured via Ingress,
make sure that traffic from within the cluster can be proxied to the ingress target.

cmd/k8s-operator/deploy/crds,k8s-operator/apis/v1alpha1: allow to define an exit node via Connector CR.
Make it possible to define an exit node to be deployed to a Kubernetes cluster
via Connector Custom resource.
Also changes to Connector API so that one Connector corresponds
to one Tailnet node that can be either a subnet router or an exit
node or both.
The Kubernetes operator parses Connector custom resource and,
if .spec.isExitNode is set, configures that Tailscale node deployed
for that connector as an exit node.
