Provide a way to opt in to the navigation alpha and beta

Problem to solve

As we work to implement the navigation redesign, we need to provide a means for users to opt in to this experience in order to use it and provide feedback (feedback mechanism may be a separate issue).

Intended users

• All

Proposal

• Add a Toggle switch in User Profile Menu - see Design Management
• Toggle opts-in to the Navigation Alpha (non-supported and will be broken)
• Once feature-complete, we begin Navigation Beta (non-supported and beta testing).
  • For some, the toggle will be disabled, they will receive the Current OR Beta navigation UI and participate in tests.

Documentation

• Add page in GitLab Docs for switching to North Star opt-in @rdickenson
  • Note that if beta's are running it may not be available

Data

• Determine how we'll track clicks in both states (Old nav vs North Star) @mikegreiling @thutterer

• Determine how we can query for all users who have this setting turned on @thutterer

  UserPreference.where(use_new_navigation: true).count

Testing

What does success look like, and how can we measure that?

• We can detect who has the opt-in switched on in the data
• We can seamlessly switch between both states and are able to have the events update accordingly

Resources

• Figma File
• Prototype

Tasks

• Include a toggle within the User menu to turn on/off the navigation redesign
• Clicking any portion of the dropdown option updates the toggle (user doesn't have to click specifically on the toggle element)
