Previously, the operator checked the ProxyGroup status fields for
information on how many of the proxies had successfully authed. Use
their state Secrets instead as a more reliable source of truth.
containerboot has written device_fqdn and device_ips keys to the
state Secret since inception, and pod_uid since 1.78.0, so there's
no need to use the API for that data. Read it from the state Secret
for consistency. However, to ensure we don't read data from a
previous run of containerboot, make sure we reset containerboot's
state keys on startup.
One other knock-on effect of that is ProxyGroups can briefly be
marked not Ready while a Pod is restarting. Introduce a new
ProxyGroupAvailable condition to more accurately reflect
when downstream controllers can implement flows that rely on a
ProxyGroup having at least 1 proxy Pod running.

Adds Recorder fields to configure the name and annotations of the ServiceAccount
created for and used by its associated StatefulSet. This allows the created Pod
to authenticate with AWS without requiring a Secret with static credentials,
using AWS' IAM Roles for Service Accounts feature, documented here:

Update the HA Ingress controller to wait until it sees AdvertisedServices
config propagated into at least 1 Pod's prefs before it updates the status
on the Ingress, to ensure the ProxyGroup Pods are ready to serve traffic
before indicating that the Ingress is ready

Every so often, the ProxyGroup and other controllers lose an optimistic locking race
with other controllers that update the objects they create. Stop treating
this as an error event, and instead just log an info level log line for it.

Implements the controller for the new ProxyGroup CRD, designed for
running proxies in a high availability configuration. Each proxy gets
its own config and state Secret, and its own tailscale node ID.
We are currently mounting all of the config secrets into the container,
but will stop mounting them and instead read them directly from the kube
API once #13578 is implemented.

The ProxyGroup CRD specifies a set of N pods which will each be a
tailnet device, and will have M different ingress or egress services
mapped onto them. It is the mechanism for specifying how highly
available proxies need to be. This commit only adds the definition, no
controller loop, and so it is not currently functional.
This commit also splits out TailnetDevice and RecorderTailnetDevice
into separate structs because the URL field is specific to recorders,
but we want a more generic struct for use in the ProxyGroup status field.

cmd/k8s-operator,k8s-operator,kube: Add TSRecorder CRD + controller
Deploys tsrecorder images to the operator's cluster. S3 storage is
configured via environment variables from a k8s Secret. Currently
only supports a single tsrecorder replica, but I've tried to take early
steps towards supporting multiple replicas by e.g. having a separate
secret for auth and state storage.
Example CR:
```yaml
apiVersion: tailscale.com/v1alpha1
kind: Recorder
metadata:
name: rec
spec:
enableUI: true
```
