Describe the bug
HPA for Loki-indexer in a failed state when zoneAwareReplication is set to enabled

To Reproduce

• add HPA for indexer

ingester:
  zoneAwareReplication:
    enabled: true
  autoscaling:
    enabled: true
    minReplicas: 1
    maxReplicas: 15
    targetCPUUtilizationPercentage: 80
    targetMemoryUtilizationPercentage: 80

kubectl describe hpa loki-ingester -n monitoring

---snip---
  Warning  FailedGetScale  30s (x6119 over 25h)  horizontal-pod-autoscaler  statefulsets.apps "loki-ingester" not found

There is no loki-ingester statefulset. There are instead the 3 zone aware statefulsets.

Expected behavior

expect to see HPA working with the zone aware statefulsets.

Environment:

• Infrastructure: Kubernettes
• Deployment tool: helm
