options:
  --help                help for help if you need some help
  --quiet               Won't print start/end/failed messages in PR
  --clean               Clean up the previous bot's & author's comments in PR
  --image IMAGE         Override docker image '--image
                        docker.io/paritytech/ci-unified:latest'

### Command 'bench'
