Connecting the new "Data" page to workbench via one-click register-approve-add-start process:

Use case:

• The "Data" page contains a link to launch the NBI jupyter notebook on workbench
  • https://www.wb.nds.org/quickstart?service=jupyternbi
• When the user clicks on the link, they are taken to the running Jupyter environment in Workbench.

Basic flow:

• Is the user authenticated?
  • No
    
    • Redirect to sign-in/register page (with quickstart request)
    • User has an account
      • No
        
        • User goes through register/verify/approve process
        • /#/register?next=<quickstart url>
        • On approval, service is added and quickstart link sent in approval email.
      • Yes
        • /#/sign-in?next=<quickstart url>
        • After successful sign-in, service is added, started, and user is redirected to running instance
  • Yes
    • Service is already added
      • No
        • Add, start and redirect to running service
      • Yes
        
        • Service is started
          • Yes
            • Redirect to running service (first)
          • No
            • Start service, redirect to running service

What needs to be done:

Assumptions:

• Single-service stack (no multi-service or optional-service stacks, for now)
• Storing the token as a cookie?
• Modify stack endpoint to support quick-start functionality (i.e., add spec parameter means add + start)
• This doesn't solve basic auth for sure.
