* cmd/containerboot,util/linuxfw: support proxy backends specified by DNS name
Adds support for optionally configuring containerboot to proxy
traffic to backends configured by passing TS_EXPERIMENTAL_DEST_DNS_NAME env var
to containerboot.
Containerboot will periodically (every 10 minutes) attempt to resolve
the DNS name and ensure that all traffic sent to the node's
tailnet IP gets forwarded to the resolved backend IP addresses.
Currently:
- if the firewall mode is iptables, traffic will be load balanced
accross the backend IP addresses using round robin. There are
no health checks for whether the IPs are reachable.
- if the firewall mode is nftables traffic will only be forwarded
to the first IP address in the list. This is to be improved.
* cmd/k8s-operator: support ExternalName Services
Adds support for exposing endpoints, accessible from within
a cluster to the tailnet via DNS names using ExternalName Services.
This can be done by annotating the ExternalName Service with
tailscale.com/expose: "true" annotation.
The operator will deploy a proxy configured to route tailnet
traffic to the backend IPs that service.spec.externalName
resolves to. The backend IPs must be reachable from the operator's
namespace.

There is an undocumented 16KiB limit for text log messages.
However, the limit for JSON messages is 256KiB.
Even worse, logging JSON as text results in significant overhead
since each double quote needs to be escaped.
Instead, use logger.Logf.JSON to explicitly log the info as JSON.
We also modify osdiag to return the information as structured data
rather than implicitly have the package log on our behalf.
This gives more control to the caller on how to log.

Kubernetes cluster domain defaults to 'cluster.local', but can also be customized.
We need to determine cluster domain to set up in-cluster forwarding to our egress proxies.
This was previously hardcoded to 'cluster.local', so was the egress proxies were not usable in clusters with custom domains.
This PR ensures that we attempt to determine the cluster domain by parsing /etc/resolv.conf.
In case the cluster domain cannot be determined from /etc/resolv.conf, we fall back to 'cluster.local'.

Changes made:
* Avoid "encoding/json" for JSON processing, and instead use
"github.com/go-json-experiment/json/jsontext".
Use jsontext.Value.IsValid for validation, which is much faster.
Use jsontext.AppendQuote instead of our own JSON escaping.
* In drainPending, use a different maxLen depending on lowMem.
In lowMem mode, it is better to perform multiple uploads
than it is to construct a large body that OOMs the process.
* In drainPending, if an error is encountered draining,
construct an error message in the logtail JSON format
rather than something that is invalid JSON.
* In appendTextOrJSONLocked, use jsontext.Decoder to check
whether the input is a valid JSON object. This is faster than
the previous approach of unmarshaling into map[string]any and
then re-marshaling that data structure.
This is especially beneficial for network flow logging,
which produces relatively large JSON objects.
* In appendTextOrJSONLocked, enforce maxSize on the input.
If too large, then we may end up in a situation where the logs
can never be uploaded because it exceeds the maximum body size
that the Tailscale logs service accepts.
* Use "tailscale.com/util/truncate" to properly truncate a string
on valid UTF-8 boundaries.
* In general, remove unnecessary spaces in JSON output.

name old time/op new time/op delta
WriteText 776ns ± 2% 596ns ± 1% -23.24% (p=0.000 n=10+10)

cmd/tailscale/cli: respect $KUBECONFIG
* `$KUBECONFIG` is a `$PATH`-like: it defines a *list*.
`tailscale config kubeconfig` works like the rest of the
ecosystem so that if $KUBECONFIG is set it will write to the first existant file in the list, if none exist then
the final entry in the list.
* if `$KUBECONFIG` is an empty string, the old logic takes over.
Notes:
* The logic for file detection is inlined based on what `kind` does.
Technically it's a race condition, since the file could be removed/added
in between the processing steps, but the fallout shouldn't be too bad.
https://github.com/kubernetes-sigs/kind/blob/v0.23.0-alpha/pkg/cluster/internal/kubeconfig/internal/kubeconfig/paths.go
* The sandboxed (App Store) variant relies on a specific temporary
entitlement to access the ~/.kube/config file.
The entitlement is only granted to specific files, and so is not
applicable to paths supplied by the user at runtime.
While there may be other ways to achieve this access to arbitrary
kubeconfig files, it's out of scope for now.

* cmd/k8s-nameserver,k8s-operator: add a nameserver that can resolve ts.net DNS names in cluster.
Adds a simple nameserver that can respond to A record queries for ts.net DNS names.
It can respond to queries from in-memory records, populated from a ConfigMap
mounted at /config. It dynamically updates its records as the ConfigMap
contents changes.
It will respond with NXDOMAIN to queries for any other record types
(AAAA to be implemented in the future).
It can respond to queries over UDP or TCP. It runs a miekg/dns
DNS server with a single registered handler for ts.net domain names.
Queries for other domain names will be refused.
The intended use of this is:
1) to allow non-tailnet cluster workloads to talk to HTTPS tailnet
services exposed via Tailscale operator egress over HTTPS
2) to allow non-tailnet cluster workloads to talk to workloads in
the same cluster that have been exposed to tailnet over their

Notably, this coverts Capabilities on the wire early to CapMap

Use the zstdframe package where sensible instead of plumbing
around our own zstd.Encoder just for stateless operations.
This causes logtail to have a dependency on zstd,
but that's arguably okay since zstd support is implicit
to the protocol between a client and the logging service.
Also, virtually every caller to logger.NewLogger was
manually setting up a zstd.Encoder anyways,
meaning that zstd was functionally always a dependency.

The derper sends an in-protocol keepalive every 60-65s, so frequent TCP
keepalives are unnecessary. In this tuning TCP keepalives should never
occur for a DERP client connection, as they will send an L7 keepalive
often enough to always reset the TCP keepalive timer. If however a
connection does not receive an ACK promptly it will now be shutdown,
which happens sooner than it would with a normal TCP keepalive tuning.
This re-tuning reduces the frequency of network traffic from derp to

seeded operations, due to the long term compiler bug around interface
parameter escapes, and the Source interface.
This change introduces the two APIs that math/rand/v2 can not yet
replace efficiently: seeded Perm() and Shuffle() operations. This
implementation chooses to use the PCG random source from math/rand/v2,
as with sufficient compiler optimization, this source should boil down
to only two on-stack registers for random state under ideal conditions.

`os.LookupEnv` may return true if the variable is present in
the environment but an empty string. We should only attempt
to set OAuth Config if thsoe values are non-empty.

Update logs for synology builds to more clearly callout which variant
is being built. The two existing variants are:
1. Sideloaded (can be manual installed on a device by anyone)
2. Package center distribution (by the tailscale team)

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.
