Fix/caddy frontend server via rfc

• Apache Trafficserver has different HTTP version on request/response, it's has been discovered during this work, but won't be fixed, noted as bug #20220315-7E5FD
• still need to find to encode the information, current idea is (published) uuid of a node (stable) + some hash of a component (or it’s name) + hash of a version
  • but maybe just uuid of a node + component is enough, as version can be concluced from the time
