Docker registry being insecure is handled by docker_registry_insecure
which is set to true by default when docker_registry is set.
The removed code had no effect because docker_registry is not changed
anyway for base (pre-upgrade) install.
This change makes config more readable and also prevents a potential
conflict with the zun profile if ever used in upgrade mode.
