Agora Contoso Supermarket fails IoT monitoring

[mes007]

Provisioned Agora Contoso Supermarket twice 99% successfully into North Europe. Found three errors on AgLogonScript.log:

Consequently, Freezer Monitoring dashboards are empty. Found from IoT Hub that no messages are received from eight IoT devices. Further debugging revealed that sensor-monitor-broker and sensor-monitor-simulator pods on Ag-AKS-Staging are in ImagePullBackOff status. From pod Events seems that container images are unavailable:
