Use js-builder consistently across the following modules:

• blueocean-core-js
• blueocean-dashboard
• blueocean-personalization
• jenkins-design-language

Other tasks:

• Add karma support to js-builder, make default
• Publish test report
• Consistent lint rules (fix warnings about invalid peer deps for eslint if possible)
• Add npm shrinkwrap
  • blueocean-core-js
  • blueocean-web, blueocean-dashboard, blueocean-personalization, blueocean-config
  • And documentation for update process
• Add script to validate package.json vs. npm-shrinkwrap.json (exists for JDL; needs to be added to others)
• Possibly add native mocha support as well? Gulp builds in blueocean-dashboard and blueocean-personalization use it but will switch to karma anyways.
