[Question] Disaggregated cluster compute group service should be headless

### Search before asking

- [X] I had searched in the [issues](https://github.com/apache/doris-operator/issues?q=is%3Aissue) and found no similar issues.

### Version

24.1.0

### What's Wrong?

The service created for disaggregated cluster compute groups is not marked headless, so the FE ping does not work when using multiple compute nodes.

In order for FE to connect to the dns entries such as .doris-compute-group.svc, the service must be marked as headless by specifying clusterIP: "None"

### What You Expected?

Expect the cluster group service to be headless by specifying clusterIP: "None" similar to fe-internal headless service to allow for FE to communicate with CG/BE.

### How to Reproduce?
