Clojurians Log v2

@borkdude I made some changes to https://go.atomist.com/catalog/skills/atomist/clj-kondo-skill around referencing config urls and hooks. The goal of this was to make it possible to reference urls like <https://github.com/borkdude/clj-kondo/tree/master/libraries/slingshot> in the configuration, and then have this library's config.edn, along with it's hooks, merged into clj-kondo's config. For me, it was an experiment to see if I could use this to develop some hooks that can be shared across all of our Clojure Repos.

Adding linting checks to a lot of existing projects has the challenge of not overwhelming people with data they might not understand. So being able to kind of tune it before making the Check visible seems really interesting to me.

Thanks for the update!
