* 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. DNSConfig CRD can be used to configure the operator to deploy kube nameserver (./cmd/k8s-nameserver) to cluster. Updates tailscale/tailscale#10499 Signed-off-by: Irbe Krumina <irbe@tailscale.com> |

Tailscale Kubernetes operator deployment manifests
./cmd/k8s-operator/deploy contain various Tailscale Kubernetes operator deployment manifests.
Helm chart
./cmd/k8s-operator/deploy/chart contains Tailscale operator Helm chart templates.
The chart templates are also used to generate the static manifest, so developers must ensure that any changes applied to the chart have been propagated to the static manifest by running go generate tailscale.com/cmd/k8s-operator
Static manifests
./cmd/k8s-operator/deploy/manifests/operator.yaml is a static manifest for the operator generated from the Helm chart templates for the operator.
