create a minimal prototype for using https://github.com/fedora-copr/logdetective as an external plugin that people can trigger to analyze logs of test lane runs.

Basically:

• create container image from fedora and dnf install logdetective binary
• attach external plugin logic
  • handle '/explain logs <test-lane-name>' comment
  • derive latest test lane run from above name
  • deduce gcs bucket url
  • call logdetective binary with url
  • attach comment (probably enclosed in folding section) 
• create plugin kubernetes manifest (derive from other plugins)
• integrate with deployment
• enable plugin in config.yaml
