Metadata of embedded volumeClaimTemplate not retained in statefulset

[diseq]

Expected behaviour

Creating a cluster with the persistent-storage.yaml shall result in a statefulset being created

Actual behaviour

Statefulset is not created as the pvc cannot be created.
Error:

create Pod rfr-redisfailover-persistent-0 in StatefulSet rfr-redisfailover-persistent failed error: failed to create PVC -rfr-redisfailover-persistent-0: PersistentVolumeClaim "-rfr-redisfailover-persistent-0" is invalid: metadata.name: Invalid value: "-rfr-redisfailover-persistent-0": a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

Cause: volumeclaimtemplate metadata of statefulset is empty

  volumeClaimTemplates:
    - kind: PersistentVolumeClaim
      apiVersion: v1
      metadata:
        creationTimestamp: null
      spec:
        accessModes:

it seems kubernetes has changed the handling of embedded metadata. prometheus operator was struggling with a similar issue

Steps to reproduce the behaviour

Deploy operator
kubectl apply -f persistent-storage.yaml

Environment

How are the pieces configured?

• Redis Operator version: chart 3.1.3, app version: 1.1.0-rc.1
• Kubernetes version: k3s v1.22.5+k3s1
• Kubernetes configuration used: vanilla, rbac active
