cmd/k8s-operator: restart ProxyGroup pods less (#14045)
We currently annotate pods with a hash of the tailscaled config so that
we can trigger pod restarts whenever it changes. However, the hash
updates more frequently than is necessary causing more restarts than is
necessary. This commit removes two causes; scaling up/down and removing
the auth key after pods have initially authed to control. However, note
that pods will still restart on scale-up/down because of the updated set
of volumes mounted into each pod. Hopefully we can fix that in a planned
follow-up PR.

cmd/k8s-operator,k8s-operator: use default ProxyClass if set for ProxyGroup (#13720)
The default ProxyClass can be set via helm chart or env var, and applies
to all proxies that do not otherwise have an explicit ProxyClass set.
This ensures proxies created by the new ProxyGroup CRD are consistent
with the behaviour of existing proxies

Nearby but unrelated changes:

* Fix up double error logs (controller runtime logs returned errors)
* Fix a couple of variable names

cmd/{containerboot,k8s-operator},k8s-operator,kube: add ProxyGroup controller (#13684)
Implements the controller for the new ProxyGroup CRD, designed for
running proxies in a high availability configuration. Each proxy gets
its own config and state Secret, and its own tailscale node ID.

We are currently mounting all of the config secrets into the container,
but will stop mounting them and instead read them directly from the kube
API once #13578 is implemented.
