* 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
MagicDNS names but on their cluster IPs.

First we had Capabilities []string. Then
https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a
superset of Capabilities. Except we never really finished the
transition inside the codebase to go all-in on CapMap. This does so.
Notably, this coverts Capabilities on the wire early to CapMap
internally so the code can only deal in CapMap, even against an old
control server.
In the process, this removes PeerChange.Capabilities support, which no
known control plane sent anyway. They can and should use
PeerChange.CapMap instead.

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.

Moving logic that manipulates a ServeConfig into recievers on the
ServeConfig in the ipn package. This is setup work to allow the
web client and cli to both utilize these shared functions to edit
the serve config.
Any logic specific to flag parsing or validation is left untouched
in the cli command. The web client will similarly manage its
validation of user's requested changes. If validation logic becomes
similar-enough, we can make a serve util for shared functionality,
which likely does not make sense in ipn.

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
client, reducing battery cost.

* cmd/k8s-operator,k8s-operator: introduce proxy configuration mechanism via ProxyClass custom resource.
ProxyClass custom resource can be used to specify customizations
for the proxy resources created by the operator.
Add a reconciler that validates ProxyClass resources
and sets a Ready condition to True or False with a corresponding reason and message.
This is required because some fields (labels and annotations)
require complex validations that cannot be performed at custom resource apply time.
Reconcilers that use the ProxyClass to configure proxy resources are expected to
verify that the ProxyClass is Ready and not proceed with resource creation
if configuration from a ProxyClass that is not yet Ready is required.
If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet.
If a tailscale Ingress has a tailscale.com/proxy-class annotation
and the referenced ProxyClass custom resource is available and Ready,
apply configuration from the ProxyClass to the proxy resources
that will be created for the Ingress.
Add a new .proxyClass field to the Connector spec.
If connector.spec.proxyClass is set to a ProxyClass that is available and Ready,
apply configuration from the ProxyClass to the proxy resources created for the Connector.
Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml. Regenerate operator.yaml
