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.

This commit modifies the kubernetes operator to allow for customisation of the tailscale
login url. This provides some data locality for people that want to configure it.
This value is set in the `loginServer` helm value and is propagated down to all resources
managed by the operator. The only exception to this is recorder nodes, where additional
changes are required to support modifying the url.

Even after we remove the deprecated API, we will want to maintain a minimal
API for internal use, in order to avoid importing the external
tailscale.com/client/tailscale/v2 package. This shim exposes only the necessary
parts of the deprecated API for internal use, which gains us the following:
1. It removes deprecation warnings for internal use of the API.
2. It gives us an inventory of which parts we will want to keep for internal use.

cmd/k8s-operator: add logic to parse L7 Ingresses in HA mode
- Wrap the Tailscale API client used by the Kubernetes Operator
into a client that knows how to manage VIPServices.
- Create/Delete VIPServices and update serve config for L7 Ingresses
for ProxyGroup.
- Ensure that ingress ProxyGroup proxies mount serve config from a shared ConfigMap.
