cmd/{k8s-nameserver,k8s-operator},k8s-operator: add a kube nameserver, make operator deploy it (#11017)
* 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.

* cmd/k8s-operator/deploy/crds,k8s-operator: add DNSConfig CustomResource Definition

DNSConfig CRD can be used to configure
the operator to deploy kube nameserver (./cmd/k8s-nameserver) to cluster.

* cmd/k8s-operator,k8s-operator: optionally reconcile nameserver resources

Adds a new reconciler that reconciles DNSConfig resources.
If a DNSConfig is deployed to cluster,
the reconciler creates kube nameserver resources.
This reconciler is only responsible for creating
nameserver resources and not for populating nameserver's records.

* cmd/{k8s-operator,k8s-nameserver}: generate DNSConfig CRD for charts, append to static manifests
