Added
- Functionality to introduce an new option for event hub configuration. Namely a source_details option 'eventhub.accessKeySecretName' to properly construct the eh_shared_key_value properly. Without this option, there were errors while connecting to the event hub service (linked to [issue-13 - java.lang.RuntimeException: non-nullable field authBytes was serialized as null 13](https://github.com/databrickslabs/dlt-meta/issues/13))
