Rewrite golang BDD tests to use scenarios

I noticed that the Golang BDD tests do not use the scenarios from [bdd/scenarios/](https://github.com/apache/iggy/tree/master/bdd/scenarios).
This should be changed. As stated in [Readme.md](https://github.com/apache/iggy/blob/master/bdd/README.md), all SDKs must use the same scenarios and be tested in the same way.

You can use [godog](https://github.com/cucumber/godog) or other framework to test with cucumber

Start by reading bdd/README.md and comparing the existing Golang BDD tests with the shared scenarios in bdd/scenarios/. Evaluate godog or another Cucumber-compatible framework, then verify that the Golang SDK runs the same scenarios and is tested in the same way as the other SDKs.
