MinIO server configuration file allows users to provide topology that allows for heterogeneous hostnames, allowing MinIO to deployed in pre-existing environments without any further OS level configurations.

### Usage

```
minio server --config config.yaml
```

- Added validation to ensure that if `service.kubernetes.io/topology-aware-hints` and `service.kubernetes.io/topology-mode` annotations are both set, they are set to the same value.Also Added deprecation warning if `service.kubernetes.io/topology-aware-hints` annotation is used.
