Code review comment for ~jslarraz/review-tools:add-component-support

Thanks @jslarraz - some initial comments - will do a more thorough review next week but so far this looks really good - just some minor things.

lpci is failing:

  :: ModuleNotFoundError: No module named 'jsonschema'

  - I think you can probably just add python3-jsonschema to the list of packages in the .launchpad.yaml to fix this

also see inline comments.
