SLES 12 HPC ARM Template deployment failed

[Azure SLES 12 HPC ARM Template](https://github.com/Azure/azure-quickstart-templates/tree/master/slurm-on-sles12-hpc)

### Issue Details

Hello,

I tried to deploy the Azure SLES 12 HPC ARM Template in the West US region with 1 Standard_A8 master node and 2 Standard_A8 worker nodes, but the deployment of the master and worker nodes failed. The error I received for each node was:

"The platform image 'SUSE:SLES-HPC:12:latest' is not available. Verify that all fields in the storage profile are correct. (Code: ImageNotFound, Target: imageReference)"

Any ideas how to fix this?

Thanks,
Max

Start with the slurm-on-sles12-hpc Azure SLES 12 HPC ARM Template linked in the issue and inspect its platform image reference. Check whether SUSE:SLES-HPC:12:latest is available in West US for the selected node sizes, then verify the template deploys successfully for the reported master and worker nodes.
