  - Call a REST API on ONTAP.
  - Cluster REST API are run using a cluster admin account.
  - Vserver REST API can be run using a vsadmin account or using vserver tunneling (cluster admin with I(vserver_) options).
  - In case of success, a json dictionary is returned as C(response).
  - In case of a REST API error, C(status_code), C(error_code), C(error_message) are set to help with diagnosing the issue,
  - and the call is reported as an error ('failed').
  - Other errors (eg connection issues) are reported as Ansible error.
