**Description**

Qubole Hook and Operator do not support `include_header` param for getting results with headers
Add Support for `include_header` get_results(... arguments=[True])
**Use case / motivation**

It's very hard to work with CSV results from db without headers. 
This is super important when using Qubole's databases.

**Are you willing to submit a PR?**

Not sure yet, I can give it a try
