minIO operator log-search-api lookup error

[Jeka-Dem]

Expected Behavior

I've set

operator:
  clusterDomain: "dev.kuber.int"

to operator deployment and for MinIO pods and prometheus it's works as expected - it change cluster.local to dev.kuber.int, but not for minio-log-search-api

Current Behavior

When MinIO Operator provides Log Search API, it tries to lookup the service by cluster.local ignoring clusterDomain parameter

E0312 13:35:46.120190       1 main-controller.go:721] error syncing 'default/minio-cms': Log Search is not ready
Get "http://minio-cms-log-search-api.default.svc.cluster.local:8080": dial tcp: lookup minio-cms-log-search-api.default.svc.cluster.local on 169.254.25.10:53: no such host

Because it's hard-coded

func (c *Controller) checkLogSearchAPIReady(tenant *miniov2.Tenant) error {
	endpoint := fmt.Sprintf("http://%s.%s.svc.cluster.local:8080", tenant.LogSearchAPIServiceName(), tenant.Namespace)
	client := http.Client{Timeout: 100 * time.Millisecond}
	resp, err := client.Get(endpoint)

and do not use env variable from GetClusterDomain function

func GetClusterDomain() string {
	once.Do(func() {
		k8sClusterDomain = env.Get(clusterDomain, "cluster.local")
	})
	return k8sClusterDomain
}

Possible Solution

Steps to Reproduce (for bugs)

1. Deploy MinIO Operator from master branch with

operator:
  clusterDomain: "some.damain"

2. Apply tenant from example with log

log:
    image: minio/logsearchapi:v4.0.2
    audit:
      diskCapacityGB: 10

3. Wail until it up
4. Check operators logs
