Allow to change the service account
As a best practice, we'd typically use Windows auth for on-prem SSAS where the SSAS service account is granted access to the data source to process the model. Allow us to change the Azure AS service account to be used when processing from SQL Server.

In Azure I believe this is meant to be managed by "Managed Service Identities' or MSI. However this seems to be inconsistently implemented though different Azure components
