Code Review

This pull request introduces support for ScyllaDB as a data source and provides a ScyllaDB CQL tool. It includes the necessary CI configuration, source and tool implementations, unit tests, and integration tests. Feedback focuses on improving JSON serialization consistency by initializing slices, adopting modern Go "any" syntax, enhancing error messages for query failures, and simplifying internal interfaces by removing unused methods.

hi @Yuan325 , can i get some guidance regarding this PR?

[Yuan325]

Hi @zseta Thank you for your contribution! Please let me know if you needs any clarifications on the feedback :)

[Yuan325]

Can we just do import github.com/scylladb/gocql within the packages instead? That way, we won't have to use the replace directive incase it causes a problem to other sources in the future.

[zseta]

@Yuan325 Unfortunately replace is the only way now. In the next major version of the scylla driver it will be fixed. Is this a blocker?

[zseta]

Thanks for the comments @Yuan325 I resolved most of the issues. The only problem is with importing (#3119 (comment)). I hope it's not a blocker, if it is then we will need to wait for a fix on our end before merging this.

I also edited the integration test so it uses containers - couldn't run it though so please check.
