Interactively run notebook as Service Principal, Workspace Identity or Managed Identity

[frithjof_v]

Please make it possible to interactively run a Notebook as a Workspace Identity, Service Principal or Managed Identity.

Purpose:

• This would allow us to connect to resources that our personal user account doesn't have access to.
• This would allow us to interactively test notebooks using the Workspace Identity, Service Principal or Managed Identity before we include the notebook in a pipeline. This way, we could test: the identity's access to data sources and the notebook code's functional compatibility with running as SPN/WI/MI (because not all notebook functionality like semantic link is compatible with SPN, we'd like to be able to test this interactively before including the notebook in a pipeline).
