Currently we  have our regex which checks `^[a-z0-9]{1,25}$`. Anyway if we create generic listener which will have more than 11 chars the Kubernetes will do not accept this name because of internal validation of name ports

```
Pod "my-cluster-kafka-0" is invalid: [spec.containers[0].ports[1].name: Invalid value: "tcp-rwfzfnconlsffwttambp": must be no more than 15 characters, spec.containers[0].ports[2].name: Invalid value: "tcp-gfyidpdeahyancys": must be no more than 15 characters, spec.containers[0].ports[3].name: Invalid value: "tcp-mccfzbfzbwsalpitwwtflx": must be no more than 15 characters]
```

This problem causing that Kafka pods never deploy until timeout.
