[FEATURE REQUEST]: Support AAD Auth when connecting to Azure Event hub

**Is your feature request related to a problem? Please describe.**
Azure event hub library supports AAD Auth when connecting to azure event hubs as documented here. https://github.com/Azure/azure-event-hubs-spark/blob/master/docs/use-aad-authentication-to-connect-eventhubs.md

We are primarily interested in connecting to event hubs with service principal + certificate. And we need to use the parameters options to pass down the service principal, certificate settings option to the call back class such that we can use the appropriate settings for different environments / clouds.

**Describe the solution you'd like**
We are looking for options such that we can send down the event hub configuration settings for our dotnet for spark jobs such that it can connect to event hubs via aad auth.

If this is already doable in dotnet for spark please enlighten us.

**Describe alternatives you've considered**
