At a quick glance, the main parts that I noticed is that since we don't emulate eventhub locally or in docker in any way, we need to add some more credential options.
Usually the Connection String or some sort of credentials file option would be great, and default back (with a log entry) when no credentials are found, that its going to use default or environment variable instead.

Check the golangci-lint output as well :)

[marc-gr]

It looks nice!

I wonder if we could add some tests for it if possible and to add some docs about how to use it.

I think this needs docs and probably at least one example configuration to help users understand how to hold it.

Raised Azure/azure-sdk-for-go#21758 for adding support for emulator in Azurite for Event Hub.
