Tom Proctor f421907c38 all-kube: create Tailscale Service for HA kube-apiserver ProxyGroup (#16572) ... Adds a new reconciler for ProxyGroups of type kube-apiserver that will provision a Tailscale Service for each replica to advertise. Adds two new condition types to the ProxyGroup, TailscaleServiceValid and TailscaleServiceConfigured, to post updates on the state of that reconciler in a way that's consistent with the service-pg reconciler. The created Tailscale Service name is configurable via a new ProxyGroup field spec.kubeAPISserver.ServiceName, which expects a string of the form "svc:<dns-label>". Lots of supporting changes were needed to implement this in a way that's consistent with other operator workflows, including: * Pulled containerboot's ensureServicesUnadvertised and certManager into kube/ libraries to be shared with k8s-proxy. Use those in k8s-proxy to aid Service cert sharing between replicas and graceful Service shutdown. * For certManager, add an initial wait to the cert loop to wait until the domain appears in the devices's netmap to avoid a guaranteed error on the first issue attempt when it's quick to start. * Made several methods in ingress-for-pg.go and svc-for-pg.go into functions to share with the new reconciler * Added a Resource struct to the owner refs stored in Tailscale Service annotations to be able to distinguish between Ingress- and ProxyGroup- based Services that need cleaning up in the Tailscale API. * Added a ListVIPServices method to the internal tailscale client to aid cleaning up orphaned Services * Support for reading config from a kube Secret, and partial support for config reloading, to prevent us having to force Pod restarts when config changes. * Fixed up the zap logger so it's possible to set debug log level.
