With T144542: Enable config deploys for service::node services done, we can now use Scap for config deploys. This means that we can move CXServer's config from ops/puppet into its deploy directory.
- identify the Puppet-controlled variables, such as passwords, API keys and host IPs/URIs
- rewrite the full config as a Jinja2 template (with ERB syntax)
- activate the config deploy in ops/puppet
