The new read-only mode is only accessible when running `tailscale web`
by passing a new `-readonly` flag. This new mode is identical to the
existing login mode with two exceptions:
- the management client in tailscaled is not started (though if it is
already running, it is left alone)
- the client does not prompt the user to login or switch to the
management client. Instead, a message is shown instructing the user
to use other means to manage the device.

* 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.

gitops-pusher supports authenticating with an API key or OAuth
credentials (added in #7393). You shouldn't ever use both of those
together, so we error if both are set.
In tailscale/gitops-acl-action#24, OAuth support is being added to the
GitHub action. In that environment, both the TS_API_KEY and OAuth
variables will be set, even if they are empty values. This causes an
error in gitops-pusher which expects only one to be set.
Update gitops-pusher to check that only one set of environment variables
are non-empty, rather than just checking if they are set.

When running as non-root non-operator user, you get this error:
```
$ tailscale serve 8080
Access denied: watch IPN bus access denied, must set ipn.NotifyNoPrivateKeys when not running as admin/root or operator
Use 'sudo tailscale serve 8080' or 'tailscale up --operator=$USER' to not require root.
```
It should fail, but the error message is confusing.
With this fix:
```
$ tailscale serve 8080
sending serve config: Access denied: serve config denied
Use 'sudo tailscale serve 8080' or 'tailscale up --operator=$USER' to not require root.

cmd/k8s-operator: fix base truncating for extra long Service names
StatefulSet names for ingress/egress proxies are calculated
using Kubernetes name generator and the parent resource name
as a base.
The name generator also cuts the base, but has a higher max cap.
This commit fixes a bug where, if we get a shortened base back
from the generator, we cut off too little as the base that we
have cut will be passed into the generator again, which will
then itself cut less because the base is shorter- so we end up
with a too long name again.

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.

* k8s-operator,cmd/k8s-operator,Makefile,scripts,.github/workflows: add Connector kube CRD.
Connector CRD allows users to configure the Tailscale Kubernetes operator
to deploy a subnet router to expose cluster CIDRs or
other CIDRs available from within the cluster
to their tailnet.
Also adds various CRD related machinery to
generate CRD YAML, deep copy implementations etc.
Engineers will now have to run
'make kube-generate-all` after changing kube files
to ensure that all generated files are up to date.
* cmd/k8s-operator,k8s-operator: reconcile Connector resources
Reconcile Connector resources, create/delete subnetrouter resources in response to changes to Connector(s).
Connector reconciler will not be started unless
ENABLE_CONNECTOR env var is set to true.
This means that users who don't want to use the alpha
Connector custom resource don't have to install the Connector
CRD to their cluster.
For users who do want to use it the flow is:
- install the CRD
- install the operator (via Helm chart or using static manifests).
For Helm users set .values.enableConnector to true, for static
manifest users, set ENABLE_CONNECTOR to true in the static manifest.

This uses the fact that we've received a frame from a given DERP region
within a certain time as a signal that the region is stil present (and
thus can still be a node's PreferredDERP / home region) even if we don't
get a STUN response from that region during a netcheck.
This should help avoid DERP flaps that occur due to losing STUN probes
while still having a valid and active TCP connection to the DERP server.
