Add pedantic setting for strict-on-deps but sloppy-on-plugins

[shmish111]

If a plugin causes a version range etc then :pedantic? :abort will abort the build however plugins are optional and can be global in profiles.clj. I don't necessarily want my build to fail because a global lint plugin I use gives version problems as this is in no way involved in my actual build, I may not ever use this plugin for this project. I think it should only be an option such as :pedantic? :plugin-abort.
