cmd/containerboot,cmd/k8s-operator: enable IPv6 for fqdn egress proxies
Don't skip installing egress forwarding rules for IPv6 (as long as the host
supports IPv6), and set headless services `ipFamilyPolicy` to
`PreferDualStack` to optionally enable both IP families when possible. Note
that even with `PreferDualStack` set, testing a dual-stack GKE cluster with
the default DNS setup of kube-dns did not correctly set both A and
AAAA records for the headless service, and instead only did so when
switching the cluster DNS to Cloud DNS. For both IPv4 and IPv6 to work
simultaneously in a dual-stack cluster, we require headless services to
return both A and AAAA records.
If the host doesn't support IPv6 but the FQDN specified only has IPv6
addresses available, containerboot will exit with error code 1 and an
error message because there is no viable egress route.

Adds a new TailscaleProxyReady condition type for use in corev1.Service
conditions.
Also switch our CRDs to use metav1.Condition instead of
ConnectorCondition. The Go structs are seralized identically, but it
updates some descriptions and validation rules. Update k8s
controller-tools and controller-runtime deps to fix the documentation
generation for metav1.Condition so that it excludes comments and
TODOs.
Stop expecting the fake client to populate TypeMeta in tests. See
kubernetes-sigs/controller-runtime#2633 for details of the change.
Finally, make some minor improvements to validation for service hostnames.

Add new fields TailnetIPs and Hostname to Connector Status. These
contain the addresses of the Tailscale node that the operator created
for the Connector to aid debugging.
