Just"slave" terminology was deprecated in Jenkins 2.0, but there are still occurrences in Jenkins Plugins and documentation. We need to keep clean it up. This EPIC keeps a track of missing renamings renaming when I we occasionally notice them.
Renaming scope includes: * Jenkins Documentation (jenkins.io, plugin docs, etc.) * Built-in plugin documentation and Web UI * Plugin Names * REST API endpoints * Symbols for JCasC/JobDSL/Pipeline * 3rd-party blogposts * Class Names and API where feasible (Retaining binary compatibility may require a massive effort) * Any other code: local variables, class fields, etc. * etc.
