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
```

Rename kube/{types,client,api} -> kube/{kubetypes,kubeclient,kubeapi}
so that we don't need to rename the package on each import to
convey that it's kubernetes specific.

Further split kube package into kube/{client,api,types}. This is so that
consumers who only need constants/static types don't have to import
the client and api bits.

Add an additional RecorderAddrs field to tailscale.com/cap/kubernetes
capability. RecorderAddrs will only be populated by control
with the addresses of any tsrecorder tags set via Recorder.

This PR is in prep of adding logic to control to be able to parse
tailscale.com/cap/kubernetes grants in control:
- moves the type definition of PeerCapabilityKubernetes cap to a location
shared with control.
- update the Kubernetes cap rule definition with fields for granting
kubectl exec session recording capabilities.
- adds a convenience function to produce tailcfg.RawMessage from an
arbitrary cap rule and a test for it.
An example grant defined via ACLs:
"grants": [{
"src": ["tag:eng"],
"dst": ["tag:k8s-operator"],
"app": {
"tailscale.com/cap/kubernetes": [{
"recorder": ["tag:my-recorder"]
“enforceRecorder”: true
}],
},
}
]
This grant enforces `kubectl exec` sessions from tailnet clients,
matching `tag:eng` via API server proxy matching `tag:k8s-operator`
to be recorded and recording to be sent to a tsrecorder instance,
matching `tag:my-recorder`.
The type needs to be shared with control because we want
control to parse this cap and resolve tags to peer IPs.

cmd/containerboot,kube,ipn/store/kubestore: allow interactive login and empty state Secrets, check perms
* Allow users to pre-create empty state Secrets
* Add a fake internal kube client, test functionality that has dependencies on kube client operations.
* Fix an issue where interactive login was not allowed in an edge case where state Secret does not exist
* Make the CheckSecretPermissions method report whether we have permissions to create/patch a Secret if it's determined that these operations will be needed

We would call Update on the secret, but that was racey and would occasionaly
fail. Instead use patch whenever we can.
Fixes errors like

For stores like k8s secrets we need to dial out to the k8s API as though Tailscale
wasn't running. The issue currently only manifests when you try to use an exit node
while running inside a k8s cluster and are trying to use Kubernetes secrets as the
backing store.
This doesn't address cmd/containerboot, which I'll do in a follow up.

We had two implemenetations of the kube client, merge them.
containerboot was also using a raw http.Transport, this also has
the side effect of making it use a http.Client

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