   1.1 Need to choose proxy type to deploy
   1.2 Add proxy to helm chart of kubetunnel-server - only deploy it if needed with the relevant config from cr spec.

@tamirshaul You should expect the following format in the KubeTunnel CR:

proxies: {
    "dcode.tech": 443,
    "rabbitmq.dcode.tech": 5672
}
