VM from user Image in Premium Storage error with Boot Diagnostics

101-vm-from-user-image: https://github.com/Azure/azure-quickstart-templates/tree/master/101-vm-from-user-image

### Issue Details
When deploying template 101-vm-from-user-image using Premium Storage Account, deployment fails due to Premium Storage not being supported for Boot Diagnostic configuration.

"code": "StorageAccountTypeNotSupported",
"message": "Storage account is of Premium_LRS type. Boot Diagnostics supports Standard_GRS,Standard_LRS,Standard_RAGRS storage account types."

Can you please include different parameters for Boot Diagnostic Storage Account or automaticaly generate a Standard Storage Account for that purpose?

### Repro steps (*if necessary, delete otherwise*)
1. Create an image under Premium Storage Account
2. Use template 101-vm-from-user-image with image created in step 1.

Start with the 101-vm-from-user-image template linked in the issue and reproduce its deployment using an image from Premium Storage. Check how Boot Diagnostics selects its storage account and verify completion with a configuration that supports Premium Storage images, either through separate parameters or an automatically created compatible account.
