cmd/k8s-operator,cmd/containerboot: add kube egress proxy (#9031)
First part of work for the functionality that allows users to create an egress
proxy to access Tailnet services from within Kubernetes cluster workloads.
This PR allows creating an egress proxy that can access Tailscale services over HTTP only.

Updates tailscale/tailscale#8184

0c6fe94cf4 cmd/k8s-operator: add matching family addresses to status
This was added in 3451b89e5f, but
resulted in the v6 Tailscale address being added to status when
when the forwarding only happened on the v4 address.

c8dea67cbf cmd/k8s-operator: add support for Ingress resources
Previously, the operator would only monitor Services and create
a Tailscale StatefulSet which acted as a L3 proxy which proxied
traffic inbound to the Tailscale IP onto the services ClusterIP.

This extends that functionality to also monitor Ingress resources
where the `ingressClassName=tailscale` and similarly creates a
Tailscale StatefulSet, acting as a L7 proxy instead.

Users can override the desired hostname by setting:

```
- tls
  hosts:
  - "foo"
```

Hostnames specified under `rules` are ignored as we only create a single
host. This is emitted as an event for users to see.

Fixes #7895

12ac672542 cmd/k8s-operator: handle changes to services w/o teardown
Previously users would have to unexpose/expose the service in order to
change Hostname/TargetIP. This now applies those changes by causing a
StatefulSet rollout now that a61a9ab087 is in.

7f6bc52b78 cmd/k8s-operator: refactor operator code
It was jumbled doing a lot of things, this breaks it up into
the svc reconciliation and the tailscale sts reconciliation.

4664318be2 client/tailscale: revert CreateKey API change, add Client.CreateKeyWithExpiry
The client/tailscale is a stable-ish API we try not to break. Revert
the Client.CreateKey method as it was and add a new
CreateKeyWithExpiry method to do the new thing. And document the
expiry field and enforce that the time.Duration can't be between in
range greater than 0 and less than a second.

Updates #8124 (reverts it, effectively)

ci: add more lints (#7909)
This is a follow-up to #7905 that adds two more linters and fixes the corresponding findings. As per the previous PR, this only flags things that are "obviously" wrong, and fixes the issues found.

71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

835a73cc1f cmd/k8s-operator: remove unnecessary timed requeue.
Previously, we had to do blind timed requeues while waiting for
the tailscale hostname, because we looked up the hostname through
the API. But now the proxy container image writes back its hostname
to the k8s secret, so we get an event-triggered reconcile automatically
when the time is right.

d857fd00b3 cmd/k8s-operator: sprinkle debug logging throughout.
As is convention in the k8s world, use zap for structured logging. For
development, OPERATOR_LOGGING=dev switches to a more human-readable output
than JSON.

8ccd707218 cmd/k8s-operator: remove times requeues in proxy deletion path.
Our reconcile loop gets triggered again when the StatefulSet object
finally disappears (in addition to when its deletion starts, as indicated
by DeletionTimestamp != 0). So, we don't need to queue additional
reconciliations to proceed with the remainder of the cleanup, that
happens organically.

c902190e67 cmd/k8s-operator: factor out some of the larger expected test outputs.
For other test cases, the operator is going to produce similar generated
objects in several codepaths, and those objects are large. Move them out
to helpers so that the main test code stays a bit more intelligible.

The top-level Service that we start and end with remains in the main test
body, because its shape at the start and end is one of the main things that
varies a lot between test cases.
