test step

1. add a secret with google service token with storage admin role

apiVersion: v1
kind: Secret
metadata:
  name: gcs-secretkey
  namespace: cluster-sample-ns
data:
  GCS_KEY_DATA: <base64 encoded of the token file content>

2. change storage spec of HarborCluster

spec:
  storage:
    kind: Gcs
    spec:
      redirect:
        enable: true
      gcs:
        keyDataRef: gcs-secretkey
        bucket: thebucketname
        pathPrefix: harbor-operator/test
