cmd/k8s-operator,k8s-operator: add topology spread constraints to ProxyClass (#13959)
Now when we have HA for egress proxies, it makes sense to support topology
spread constraints that would allow users to define more complex
topologies of how proxy Pods need to be deployed in relation with other
Pods/across regions etc.

cmd/k8s-operator,k8s-operator,go.{mod,sum}: publish proxy status condition for annotated services (#12463)
Adds a new TailscaleProxyReady condition type for use in corev1.Service
conditions.

Also switch our CRDs to use metav1.Condition instead of
ConnectorCondition. The Go structs are seralized identically, but it
updates some descriptions and validation rules. Update k8s
controller-tools and controller-runtime deps to fix the documentation
generation for metav1.Condition so that it excludes comments and
TODOs.

Stop expecting the fake client to populate TypeMeta in tests. See
kubernetes-sigs/controller-runtime#2633 for details of the change.

Finally, make some minor improvements to validation for service hostnames.

Fixes #12216

cmd/k8s-operator,k8s-operator: allow proxies accept advertized routes. (#12388)
Add a new .spec.tailscale.acceptRoutes field to ProxyClass,
that can be optionally set to true for the proxies to
accept routes advertized by other nodes on tailnet (equivalent of
setting --accept-routes to true).

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.

cmd/k8s-operator,k8s-operator: optionally serve tailscaled metrics on Pod IP (#11699)
Adds a new .spec.metrics field to ProxyClass to allow users to optionally serve
client metrics (tailscaled --debug) on <Pod-IP>:9001.
Metrics cannot currently be enabled for proxies that egress traffic to tailnet
and for Ingress proxies with tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation
(because they currently forward all cluster traffic to their respective backends).

The assumption is that users will want to have these metrics enabled
continuously to be able to monitor proxy behaviour (as opposed to enabling
them temporarily for debugging). Hence we expose them on Pod IP to make it
easier to consume them i.e via Prometheus PodMonitor.

cmd/k8s-operator,k8s-operator: allow users to configure proxy env vars via ProxyClass (#11743)
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: proxy configuration mechanism via a new ProxyClass custom resource (#11074)
* 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
