cmd/k8s-operator,k8s-operator,go.{mod,sum}: make individual proxy images/image pull policies configurable
Allow to configure images and image pull policies for individual proxies
via ProxyClass.Spec.StatefulSet.Pod.{TailscaleContainer,TailscaleInitContainer}.Image,
and ProxyClass.Spec.StatefulSet.Pod.{TailscaleContainer,TailscaleInitContainer}.ImagePullPolicy
fields.
Document that we have images in ghcr.io on the relevant Helm chart fields.
Updates tailscale/tailscale#11675

Adds new ProxyClass.spec.statefulSet.pod.{tailscaleContainer,tailscaleInitContainer}.Env field
that allow users to provide key, value pairs that will be set as env vars for the respective containers.
Allow overriding all containerboot env vars,
but warn that this is not supported and might break (in docs + a warning when validating ProxyClass).

* 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
