cmd/k8s-operator,k8s-operator: add topology spread constraints to ProxyClass (#13959) 
Now when we have HA for egress proxies, it makes sense to support topology
spread constraints that would allow users to define more complex
topologies of how proxy Pods need to be deployed in relation with other
Pods/across regions etc.

Updates tailscale/tailscale#13406

#### DNSConfig
DNSConfig can be deployed to cluster to make a subset of Tailscale MagicDNS
names resolvable by cluster workloads. Use this if: A) you need to refer to
tailnet services, exposed to cluster via Tailscale Kubernetes operator egress
proxies by the MagicDNS names of those tailnet services (usually because the
services run over HTTPS)
B) you have exposed a cluster workload to the tailnet using Tailscale Ingress
and you also want to refer to the workload from within the cluster over the
Ingress's MagicDNS name (usually because you have some callback component
that needs to use the same URL as that used by a non-cluster client on
tailnet).
When a DNSConfig is applied to a cluster, Tailscale Kubernetes operator will
deploy a nameserver for ts.net DNS names and automatically populate it with records
for any Tailscale egress or Ingress proxies deployed to that cluster.
Currently you must manually update your cluster DNS configuration to add the
IP address of the deployed nameserver as a ts.net stub nameserver.
Instructions for how to do it:
https://kubernetes.io/docs/tasks/administer-cluster/dns-custom-nameservers/#configuration-of-stub-domain-and-upstream-nameserver-using-coredns (for CoreDNS),
https://cloud.google.com/kubernetes-engine/docs/how-to/kube-dns (for kube-dns).
Tailscale Kubernetes operator will write the address of a Service fronting
the nameserver to dsnconfig.status.nameserver.ip.
DNSConfig is a singleton - you must not create more than one.
NB: if you want cluster workloads to be able to refer to Tailscale Ingress
using its MagicDNS name, you must also annotate the Ingress resource with
tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation to
ensure that the proxy created for the Ingress listens on its Pod IP address.
NB: Clusters where Pods get assigned IPv6 addresses only are currently not supported.

given ProxyClass to resources created for a Connector, use
connector.spec.proxyClass field.
ProxyClass is a cluster scoped resource.
