Azure Batch Executor : support for Service Principal Auth

[KrisJanssen]

Usage scenario

Azure Batch supports multiple usage styles: A Batch Service can have a public endpoint or a private one and nodes can be provisioned in a Batch managed subscription or in the user subscription.

When wanting to use (more secure) private endpoints and user subscription provisioning, key based authentication is not available. AAD Service Principal authentication must be used as per : https://docs.microsoft.com/en-us/azure/batch/batch-aad-auth

Suggest implementation

To make NextFlow more usable in these scenarios an option should be added to choose between either key based or SP based authentication.

Hi @KrisJanssen

Thanks for raising this request - I'm looking into this and would really appreciate if you could please share further information on your use case w.r.t Azure Batch account settings such as System Managed Identity as well as Pool level settings specific to your use-case.
