Honor namespace local configuration of clj-kondo

[OknoLombarda]

refactor-nrepl already honors clj-kondo's global config for unused namespaces, but maybe it would be right to also check namespace local configuration?

I'd be fine with this, thanks for the proposal!

@OknoLombarda: did you have in mind to offer a PR?

[OknoLombarda]

Yeah, I just don't have much time lately. I'll try to do it on this weekend. Also, clj-kondo supports namespace local configuration via namespace metadata, but that's probably gonna be too much? I guess I'll just add :config-in-ns support, at least for now

Sweet!

Both are nice, but any contribution is welcome!
