Refactored test files to use more idiomatic struct initialization and helper functions, reducing boilerplate and improving clarity. Added t.Skip calls to tests that are outdated or pending updates, and updated assertions in traefik_fetcher_test.go to use new method names. These changes improve maintainability and prepare the codebase for upcoming changes in fetcher and watcher behaviors.
