Missing system tests for Qubole provider

[mik-laj]

Hello,

We are trying to work on increasing system test coverage of all providers that require credentials to communicate with external services/systems. Currently, system tests are not run on CI, but are still very helpful if you make changes to your code and want to make sure no regression has occurred. In the future, we want to run these tests also on CI - AIP-4.

I noticed that we lack system tests for Qubole and I think it is worth adding these tests to make sure that the example DAG and documentation do not have defects.

Best regards,
Kamil Bregułaa
