Feature request

tkn-results should be tested alongside other code changes - both for unit testing and e2e testing.

Use case

• Ensure tkn-results is up to date with code features.
• Run e2e tests by issuing tkn-results commands.
• Ultimately release the tkn-results plugin alongside the api and watcher releases.
