When supplying an azure secret key to configure azure storage, sensitive data is being logged in plaintext in the operator pod. As example:
```
2021-12-07T21:33:26.585Z INFO controller-runtime.manager.controller.dataprotectionapplication Azure storage key value after parsing: uvpY7CJ5BMjwWAIKh/TLcHLzlZ/FH+fvDS91SQ2kHa4uRDUqkHPVHCxP7fpbSGv+M8SRJ7gCQjMYaV2U+ydgYg== {"reconciler group": "oadp.openshift.io", "reconciler kind": "DataProtectionApplication", "name": "velero-sample", "namespace": "openshift-adp"}

We will want to ensure all these logs are removed.
