cmd/k8s-operator: set different app type for operator with proxy (#10081)
Updates tailscale/tailscale#9222

plain k8s-operator should have hostinfo.App set to 'k8s-operator', operator with proxy should have it set to 'k8s-operator-proxy'. In proxy mode, we were setting the type after it had already been set to 'k8s-operator'

Maisem Ali 335a5aaf9a cmd/k8s-operator: add APISERVER_PROXY env
The kube-apiserver proxy in the operator would only run in
auth proxy mode but thats not always desirable. There are
situations where the proxy should just be a transparent
proxy and not inject auth headers, so do that using a new
env var APISERVER_PROXY and deprecate the AUTH_PROXY env.

THe new env var has three options `false`, `true` and `noauth`.

Maisem Ali 7f6bc52b78 cmd/k8s-operator: refactor operator code
It was jumbled doing a lot of things, this breaks it up into
the svc reconciliation and the tailscale sts reconciliation.

Prep for future commit.

Maisem Ali 24509f8b22 cmd/k8s-operator: add support for control plane assigned groups
Previously we would use the Impersonate-Group header to pass through
tags to the k8s api server. However, we would do nothing for non-tagged
nodes. Now that we have a way to specify these via peerCaps respect those
and send down groups for non-tagged nodes as well.

For tagged nodes, it defaults to sending down the tags as groups to retain
legacy behavior if there are no caps set. Otherwise, the tags are omitted.

Maisem Ali 489e27f085 cmd/k8s-operator: make auth proxy pass tags as Impersonate-Group
We were not handling tags at all, pass them through as Impersonate-Group headers.
And use the FQDN for tagged nodes as Impersonate-User.
