f53c3be07c cmd/k8s-operator: use our own container image instead of busybox
We already have sysctl in the `tailscale/tailscale` image, just use that.

1294b89792 cmd/k8s-operator: allow setting same host value for tls and ingress rules
We were too strict and required the user not specify the host field at all
in the ingress rules, but that degrades compatibility with existing helm charts.

Relax the constraint so that rule.Host can either be empty, or match the tls.Host[0]
value exactly.

335a5aaf9a cmd/k8s-operator: add APISERVER_PROXY env
The kube-apiserver proxy in the operator would only run in
auth proxy mode but thats not always desirable. There are
situations where the proxy should just be a transparent
proxy and not inject auth headers, so do that using a new
env var APISERVER_PROXY and deprecate the AUTH_PROXY env.

THe new env var has three options `false`, `true` and `noauth`.

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.

24509f8b22 cmd/k8s-operator: add support for control plane assigned groups
Previously we would use the Impersonate-Group header to pass through
tags to the k8s api server. However, we would do nothing for non-tagged
nodes. Now that we have a way to specify these via peerCaps respect those
and send down groups for non-tagged nodes as well.

For tagged nodes, it defaults to sending down the tags as groups to retain
legacy behavior if there are no caps set. Otherwise, the tags are omitted.

a7ab3429b6 cmd/k8s-operator: refactor reconcile loop, un-plumbing reconcile.Result.
We used to need to do timed requeues in a few places in the reconcile logic,
and the easiest way to do that was to plumb reconcile.Result return values
around. But now we're purely event-driven, so the only thing we care about
is whether or not an error occurred.

Incidentally also fix a very minor bug where headless services would get
completely ignored, rather than reconciled into the correct state. This
shouldn't matter in practice because you can't transition from a headful
to a headless service without a deletion, but for consistency let's avoid
having a path that takes no definite action if a service of interest does
exist.
