Hiding old cookie banner if new banner is shown - #48044

Right now, we display a banner at the bottom of the page to users in GDPR countries which tells them about our cookie / tracking policy. However, this banner is not GDPR compliant. We now have a GDPR compliant banner built by OneTrust which we want to display instead of the non-compliant banner. This PR hides the old banner whenever we have the onetrust_cookie_scripts experiment enabled.

• Hides the old cookie_banner.haml when the onetrust_cookie_scripts experiment is enabled.
• Shows the new onetrust_cookie_scripts banner when the onetrust_cookie_scripts experiment is enabled.
• Adds experiments.rb which makes it easier to hide/enable features using URL params or browser cookies (for testing purposes).

Testing story

• Added UI test
• Manually tested:
  • http://localhost.hourofcode.com:3000/uk?otgeo=gb&onetrust_cookie_scripts=production
  • http://localhost-studio.code.org:3000/courses?otgeo=gb&onetrust_cookie_scripts=production
  • http://localhost.code.org:3000/cookies?otgeo=gb&onetrust_cookie_scripts=production

Deployment strategy

• This will be deployed to production hidden behind a DCDO experiment flag. We will do a bug bash using browser cookies. Once it seems like there are no issues, we will enable the DCDO experiment flag.

Follow-up work

• Schedule a bug bash
