RH-SS0 Operator 7.4.5 Keycloak not passing Storage class information to PVC (Persistent Volume Claim)

Issue

• When Keycloak is deployed and the PVC (Persistent Volume Claim) is created for the PostgreSQL pod it is created without a storageClassName associated with it then it fails. Keycloak definition specifies a storageClassName as following:

apiVersion: keycloak.org/v1alpha1
kind: Keycloak
metadata:
  name: redhat-sso
  namespace: redhat-sso-operator
  labels:
    app: sso
spec:
  instances: 1
  externalAccess:
    enabled: True
  storageClassName: ocs-storagecluster-ceph-rbd

• This same definition works in 7.4.4.
• Due to the inability to upgrade RH-SSO Operator to 7.4.5 in several environments it's not possible to successfully install RH-SSO Operator until this issue is corrected. Also you cannot install a back-level version of RH-SSO Operator.
