cmd/containerboot: load containerboot serve config that does not contain HTTPS endpoint in tailnets with HTTPS disabled
Fixes an issue where, if a tailnet has HTTPS disabled, no serve config
set via TS_SERVE_CONFIG was loaded, even if it does not contain an HTTPS endpoint.
Now for tailnets with HTTPS disabled serve config provided to containerboot is considered invalid
(and therefore not loaded) only if there is an HTTPS endpoint defined in the config.

cmd/containerboot,kube/kubetypes,cmd/k8s-operator: detect if Ingress is created in a tailnet that has no HTTPS
This attempts to make Kubernetes Operator L7 Ingress setup failures more explicit:
- the Ingress resource now only advertises HTTPS endpoint via status.ingress.loadBalancer.hostname when/if the proxy has succesfully loaded serve config
- the proxy attempts to catch cases where HTTPS is disabled for the tailnet and logs a warning

containerboot's main.go had grown to well over 1000 lines with
lots of disparate bits of functionality. This commit is pure copy-
paste to group related functionality outside of the main function
into its own set of files. Everything is still in the main package
to keep the diff incremental and reviewable.
