Announcing Service Principal support for Fabric APIs

[evaAlroy]

A new way to authenticate and authorize your Fabric applications.

You can now use service principal to access Fabric APIs. Service principal is a security identity that you can create in Entra and assign permissions to it in Entra and other Microsoft services, such as Microsoft Fabric. 

With service principal you can automate your Fabric processes and integrate them with other services.
