cmd/{k8s-operator,k8s-nameserver},k8s-operator: update nameserver config with records for ingress/egress proxies (#11019)
cmd/k8s-operator: optionally update dnsrecords Configmap with DNS records for proxies.

This commit adds functionality to automatically populate
DNS records for the in-cluster ts.net nameserver
to allow cluster workloads to resolve MagicDNS names
associated with operator's proxies.

The records are created as follows:
* For tailscale Ingress proxies there will be
a record mapping the MagicDNS name of the Ingress
device and each proxy Pod's IP address.
* For cluster egress proxies, configured via
tailscale.com/tailnet-fqdn annotation, there will be
a record for each proxy Pod, mapping
the MagicDNS name of the exposed
tailnet workload to the proxy Pod's IP.

No records will be created for any other proxy types.
Records will only be created if users have configured
the operator to deploy an in-cluster ts.net nameserver
by applying tailscale.com/v1alpha1.DNSConfig.

It is user's responsibility to add the ts.net nameserver
as a stub nameserver for ts.net DNS names.
